I have 11k on mine, stock Maggi tune, 17k total. Of that 11k honestly apx 4000 is towing out west 6k pounds.
From all of the reading I have done, thread following etc. Dave is the brain on the tunes and issues. He still supports the platform and soon I'll do his tune. My tune has been good...
I ran 15 psi on my 285's in Moab, felt good, no issues, not super hard trails. Not sure if that helps you or not. Worked out to be bought 18 psi in the afternoon once things warmed up some.
It’s 7,6” tall and 7’ wide, so 52.5 frontal. Looks taller than it is partially because there is no awning breaking up the side.
It tows real well. V nose front. Even w side wind and simi’s it tracks well w the Anderson WD hitch.
I’ve towed probably 4K miles; Boise to Yellowstone and back...
It took some trial and error but I got mine 99.98% on.
Don’t just look at the Speedo. Do a trip set your odometer and then do a trail on your gps.
On a longer drive 100+ miles you can see what the real accuracy is.
