Ok, as of last Tuesday I have a great new Ram 2500 4x4 that I absolutely love. I bought the picture frame adapter to mount my Reese 15k Pro hitch to the puck system in the bed, and lowered the hitch to the lowest possible point (4" drop, as discussed here earlier).
Now the fun starts - If the truck goes nose down slightly, I have MAYBE 1.5" clearance between the tail and the trailer.
It was harrowing towing it home the 2 miles from the storage lot, as I was watching that gap pretty closely.
Ok, so I put the hitch back up to the old position, and gain my clearance back.
But the trailer is pretty unlevel.
So...I guess my options are:
1) lower the hitch one notch (2") but that will reduce my clearance
2) See if I can find a height increase kit as someone mentioned here (I'll call Forest River tomorrow) to bring the trailer up 2" w/ the down 2" from 1)
3) See if Ram (or an aftermarket manufacturer) has an air kit that can go on to raise and lower the height of the truck.
4) Sell the trailer and go back to a bumper pull
