Hi, I have a few questions that may be stupid, but since we have some new features on our new Big Country 2011 3450TS, that we are not to familiar with we are asking. 1 Since we camp in colder climates on our old camper we ran the furnance more on cold days( instead of electric heaters) to keep our holding tanks from freezing up. Today we found a switch that we were unaware of up by the waterpump that says heater. I assume this means tank heater? We never had this before, do you turn this switch on when it is really cold out, or can you just run your furnance, is it ducted into the water holding tank compartment. 2 I ask the service man about greaseing the auto hubs, how many miles, once a year ect, he said he would check on it, never did. We don't want to break down on the road somewhere. In the past we took our old rv down to the our local mechanic who packed the bearings about every two years. Do we change from this practice? 3 Our walk thru tech, told us on the electric awning, all you have to do is push the button. In or out. Yesterday I found on the arms, there are plastic tightners like on our non automatic awning. Do we use these? If so when. 4 We now have a pocelain toilet, what is the best thing to use to clean it? Can we use any auto cleaner like you stick to the side of the bowl ect? We just had a plastic toilet before, someone told us that with a porcelain toilet you could use a more aggresive cleaner then you could on plastic if you have to. What do you use? 5 Are the tires on our rv no good? Everything that I read on this forum says that the tires Heartland uses are junk. We had a blowout on our last rv just this year that destroyed our fender lights ect. I just installed new tires on our last rv just before we came down here to Texas, maybe I should have kept them. In this day and age I thought tires would be the last of my worries after spending a lot of money for a brand new tire. 6 Somewhat upset over a few thinks on our new camper, after reading a post on changing taillights over to LED lights, I assumed ours had LED as most all new campers have them, much to my dismay ours doesn't, but the top back clearance lights are LED! This makes it look funny at night with the different color and brightness. What gives did they make our camper with parts left over? 7 Slam doors on the storage compartment, ours doesn't have them, all the other Big Countries on the lot had them, when I questioned our salesman about it he stated that thats the way Heartland does it, you never know until you see it what it has on it. I told him that I wanted slam doors if I was indeed buying a 2011, and the others had it. None of the others were my same model though. He said sorry, if I wanted the doors I had to take one of the other models. He didn't know if he ordered another 3450Ts if it would have slam doors or not. So we took it but we are still not happy. I think a 2011 should have everything that the others have, unless it is a option. Ours was built 11/02/09 and we bought it 12/10/09. So it should have had the new improvements. Your thoughts? Overall we love it so far but just had a few questions. Thanks
