I'm considering a 21C which will be pulled with my 1st gen Tundra TRD 4X4, 7100 lb tow rating and 1330 lb CCC. The truck is kept mechanically and visually close to "showroom new"
My camping will be mostly off the grid on BLM, State & Federal parks.
I am going both airbags and a equalizer WDH set up. My thought is for hwy the airbags at 10lbs for cushion and some leveling and the WDH in place. Off road the WDH will come off and enough air in the bags to bring the trailer near level.
I can see off road with a WDH attached it could be possible to bend the WDH bars or damage the trailers frame when going through a draw with a incline going into the draw or coming out of it.
Just my thought.
For the original poster.....check tire air pressure for the weights. I have Michelins and can call them with my axle weights and they will tell me what tire pressure to have.........very handy
