    DIY Freeze Proofing / Insulating / Heat Strips / Sensors / Refrigerator

    I have a [2017] Pioneer RK280. I want to spend a week or two only in NYC in December. The temps may get below freezing. Since it will only be a short time, I do not want to deal with a skirt or anything like that -- my research shows lots of problems. DOES ANYONE HAVE EXPERIENCE WITH THIS...

    How and Should I fix/upgrade my TT brakes?

    So it's been over a month I think, as my mechanic tries to get new drums for my 2017 Heartland Pioneer 280RK with 4400 pound axles. I thought he was ordering from Dexter, but I later found he was ordering after market to save me money. He then tried Dexter, but they don't have any and are...

    Trailer Brakes Weakening

    So I figured the bearings needed repacking after a year, and so I took it to the mechanic anyway. The bearings were redone about a year ago (I paid on 3/3/22). Today, I look and my Everlance mileage logger tells me we've driven 9,330 miles since that date. Well, indeed my 10K miles or 1yr...

    Trailer Brakes Weakening

    Thanks Gary & Bob. You've both pointed directly at the brakes rather than the wiring, which is where I was getting as well. The fact that the brake signal is going well below auto ground was what got me hunting down ground lines first. But now I'm convinced that the controller has a negative...

    Trailer Brakes Weakening

    So I have this feeling that my trailer brakes aren't as strong 12 months after I first bought this used Heartland Pioneer, at which time I had the brakes checked by my own mechanic. I could be mistaken about this feeling. They never locked up on asphalt, but I have this feeling for the jerk...

    It's Time to Test the Emergency Breakaway Switch on Your Trailer

    A year ago I bought a new-to-me trailer from Gander/CampingWorld near Savannah. I've taken good care of it. I always made sure to connect the emergency brake cable (trailer breakaway cable). For reasons I won't waste your time on, I just opened up the metal junction box on my trailer's...

    Antifreeze vs Near-Empty for Winter Storage

    ...oh, more info. I'm camping southward only 3 weeks after the 12degF event. So I'm going to have to be draining (and saving for next time) all the antifreeze anyway. So do I drain and blow it out before the 12degF day, just in case, or do that 3 weeks later because I must? My tanks and...

    Antifreeze vs Near-Empty for Winter Storage

    My Travel Trailer is stored in my driveway, in the foothills north of Atlanta. Right now, my fresh tank, water heater, cabin floor and cabinet tubing, toilet and faucets are substantially filled with Antifreeze. That should be fine for 25degF weather we're having at night now. HOWEVER, a...

    If pex freezes, is damage permanent?

    BTW, I may have found my answer but SINCERELY APPRECIATE YOUR COMMENTS. At this link: https://www.irv2.com/forums/f59/pex-and-freezing-temperatures-374158.html I find the following of interest: "When a ball or piston type valve is closed while filled with water the water is trapped in the...

    If pex freezes, is damage permanent?

    I'll try to prevent my low point drains from freezing, by either keeping dry or adding a skirt or other means. But if the DO happen to freeze, is that damage to the pex pipe or value permanent or is it only a temporary problem? Same question for the general underbelly, hopefully somewhat...

    2018 Pioneer RK280 MYSTERY LIGHT SWITCH

    Found it rather quickly using the tool recommended by @mlpeloquin and described by @centerline . Thanks! It's hilarious. First of all, I don't give a rats body part about the external speakers having red LED backlighting. Second of all, why in the world would that external light be on the...

    Where might short circuit be?

    Sorry, @centerline , I thought you were referring to the link provided by @wdk450 (https://www.ebay.com/itm/1855525184...CIfogCAnvhKsC7tMWXDIycfFk=|tkp:Bk9SR_SxlITsYA) which is nothing more than a light bulb on wires, which indeed, is less useful than a multimeter. I now realize that you...

    Where might short circuit be?

    Cool! A new toy to play with. Thanks, @mlpeloquin . This uses exactly the concept I was talking about, but is in a tool where they've already figured out the details. I can support my charity via smile.amazon that I always move over to, and it seems you provided a smile link in the first...

    Where might short circuit be?

    Just between you and me, @lynndiwagoner , I appreciate your comment about the USB jack. Shop talk: yes, it might be a cheap linear regulator. I've been focused on battery operated devices for a few years, and would never use a linear regulator to get from 12V to 5V, instead opting for a...

    Where might short circuit be?

    Well, the mystery second wire on the switch controlling the indirect lighting over the slide is INDEED the problem. It didn't before, but today it measures as a short to ground and in fact blew another fuse. I have it disconnected. I confirmed it's shorted to ground at this time. I confirmed...

    2018 Pioneer RK280 MYSTERY LIGHT SWITCH

    My 2018 Heartland Pioneer RK280 has a double-switch in the hallway to the bedroom, to the right of the thermostat. Left left switch controls the outside red leds beneath the body and steps. The right switch controls the led string on the main body wall, above the slide, hidden from direct...

    Where might short circuit be?

    Thanks @2019_V22 . I'll add more clarification to the warning light in the distribution panel. If the downstream circuit can be fully turned off, such as with a light switch, then the warning light WILL go off, even with the fuse removed. But if the downstream circuit is connected full time...

    Where might short circuit be?

    Thanks, @centerline . That's what a "continuity tester" on a regular multimeter does. The multimeter also gives you other diagnostic tools. Amazon has them as cheap as $15. More digit accuracy and known brand Fluke for $237. I think the typical RVer should be fine with $15. (@wdk450...

    Where might short circuit be?

    I just temporarily separated the offending branch from the distribution center (fuse box). This was trivial enough to do. The problem is indeed in the branch and not in the distribution center board. Note that it's NOT a simple short to ground. There's at a minimum some capacitance here...

    How to remove front cover of WFCO Distribution Center

    OK, I was too impatient and I have the answer already. It was indeed the most obvious two screws at the top, plus two tabs at the bottom. The screws are behind the flip-down door, and near the left and right upper corners. Just remove those, then the cover tilts down and you can lift out from...

    How to remove front cover of WFCO Distribution Center

    I have a 2018 Heartland Pioneer PI RK 280 travel trailer with a WF-8900 series WFCO Power Center (breaker/fuse box). I need to inspect/change DC branch circuits reaching this box. The front cover removal isn't visually obvious. I'd rather not assume something snaps, but then break it. Any...

    Where might short circuit be?

    LOL, @wdk450 , I can simply use a volt meter (on continuity tester position) to see if there's a short. No need for lightbulbs or smoke/heat. That's the proper tool for this job. Remember, I'm an Electrical Engineer. I've got thousands of dollars of test equipment, and voltmeters can...

    Where might short circuit be?

    Thanks. I'm still looking for more applicable input, please. I'll explain... @lynndiwagoner , thanks for the suggestion, but I never even got to the point of adding new stuff. I was confirming the presence of 12V before adding anything. The ONLY thing I did was strip the previously straight...

    Where might short circuit be?

    I have a 2018 Heartland Pioneer PI RK 280 travel trailer. It appears that I have a WFCO Power Center (breaker/fuse box). I have an advanced degree in Electrical Engineering and I built my own house, including residential electrical. So I do know what I'm doing. Yesterday, a Power Center LED...

    Confused by black tank flush

    Ah ha... but... my toilet flush is only several ounces that happens at the time the foot pedal is pressed. There's no toilet tank for a sudden flow of volume water. No I haven't measured that volume, LOL. It's more like a "spritz" each time the foot pedal is pressed. Note I *have* been...

    Confused by black tank flush

    @NYSUPstater , your process (first paragraph) sounds essentially the same as I am proposing. Thanks. @david-steph2018 , thanks for your unreliable camp water insight. DARN, I wish there was a fast path from the fresh water tank to the black tank. Maybe I should carry a hose that fits the [to...

    Confused by black tank flush

    @david-steph2018 , please clarify this "burp" thing in detail. Perhaps because I'm an engineer, I need to fully understand what you're talking about before I can understand it at all, LOL. I get it about lightening the towing weight. That's why I'm thinking only 1/3 fresh, which we're...

    Confused by black tank flush

    I've settled on the following with regard to the black tank. Yes, I closed the dump valve and ran the flush. I was not on city water pressure and I had the pump turned off so there was no flush water. I held the toilet foot flush valve down and looked down the hole with a flashlight. I let...

    Confused by black tank flush

    I apologize for being a little bit rude in my last post, regarding black tank capacity. I don't know what got into me. In fact, the one place I can envision needing to at least have a rough estimate is in adding treatments to the tank that are volume adjusted. BTW, I do still stick by the...

    Confused by black tank flush

    I haven't really worried too much about the black tank size. I know many ways I could measure it. It takes about 2.5 minutes to fill to 1/3, using my home garden hose on the flush in-port. No pressure reducer. The flow rate is roughly the same with the vacuum breaker temporarily removed...

    Confused by black tank flush

    I very appreciate the input, sincerely, @david-steph2018 , but that install manual doesn't [directly] address my complaint. The manual doesn't show the plumbing between toilet and the tank. I believe that were I the designer of this, I would have put the nozzle in whatever pipe connects the...

    Confused by black tank flush

    So, @LBR, the implication there is that the design does NOT include a spray at the point of excrement initial contact? I can see not wanting to drill a hole in a brittle elbow, but that's how I would have designed it -- with the sprayer on the inside (upper side) of the elbow, pointing right at...

    Confused by black tank flush

    With an empty, relatively clean black tank, when I leave the dump valve closed and run water into the flush port, it takes 2 or 3 minutes for the black tank to fill to the 1/3rd level. During this time, when I shine a flashlight down through the held-open toilet valve, I can NOT see any water...
