I see the OP has already made up their mind, but just to add a little to the discussion. I have basically the same truck but am carrying a camper that weighs a less than the 811 (no I haven't been to the scales yet). To make the ride acceptable I added Helwig Load Pro springs, replaced the factory shocks, added a rear sway bar and upgraded the tires and wheels from the factory 3042lb rated to 265/75R15 3415lb rated. You are showing wisdom in taking the advice and passing on that camper.
