Sid, at 16k, I was running heavy that day. Had some water, some stuff in the tanks and a bunch of stuff for the rally. I do carry a lot normally though. I have a heavy aluminum sliding tray that holds 8 large totes full of stuff, plus a ladder, portable satellite dish and BBQ grill - all on the tray alone. My front section is loaded up with 3 steel doggy pens, 4 bag chairs, 2 lounge chairs, 2 tables, wheel chocks and more. Then there's the 2 stage water filtration system and the water softener - all 3 full of water. I also have the washer/dryer and we kepe food, dishes and clothing in the trailer at all times.
Mine adds up. Am I heavier than you'll typically run? Only you can know.
