1st Gen DC and 282BHS Bullet

[Amos & Buster]

2005 Tundra Double Cab, 4.7 4WD SR5, rhino lining, full tank of gas, 100lbs or so of dogs, misc. junk, my girlfriend and I, = 5,700lbs on the CAT scale. Front Axel wt 2560 lbs. and rear axel 3140 lbs. I'm looking into a 2009 or 2010 Keystone Bullet 282BHS. Dry weight = 5060 lbs. hitch weight is listed 540 lbs. Keystone factory rep. stated weights are accurate without 2 batteries or full LP.
My Math... 5,700 wt of truck loaded
80 est. wt. of 2 batteries
100 est. wt. of propane
5,060 wt. of dry trailer
___________________________________________
total weight = 10,940 lbs.

GCWR: 11,800 lbs.
- 10,940 lbs. truck & camper
____________________________________________
860 lbs. to spare to cover WDH & misc. gear, etc.

I realize this doesn't leave much room for gear or another passenger. What do you guys think about this combo? Any reccomended upgrades to add to make the truck perform while towing this TT? I love the truck but this towing stuff is really starting to drive me nuts...I wish it's GCWR was a little higher. Thanks.

I pulled a 26' 5'er with my 2000 Tundra, weighted in just a little over 7,000 lbs back then lightly loaded. It pulled it fine except for the 6% & 7% grades in the mountains made it work some, still got the job done though.
