Thanks for the info guys. Ron, curious how you arrived at the TW. And getting 200# back on the steer would be perfect, put it back at the original point. The airbags in the rear coils allow me to maintain desired ride height.
Thinking about this I realize I can remove about 50 lbs from the tongue by draining the HW heater, it's right at the front of the camper. I haven't looked yet but I presume I can install some sort of quick drain?
I'm switching hitches on Monday after the rain ends. Going from a cast shank and round bars to a steel shank with Trunnions. And Dual Cams. I modified the shank to move the ball forward about three inches. I'll put up pics of the before and after setup.
