A 30 footer is real long for the twisty and narrow forest roads out west -- maybe conditions are easier when boondocking elsewhere back east?? A lightweight trailer is ok for boondocking -- just take it slow on rough roads. If you are interested, maybe check out my blog links in my signature -- we do a lot of very rough camping with a small ultralight. But this is not rock-hopping -- we travel at 5 or 10 mph on really bad roads, and we roll very slowly over big rocks and potholes.
If you really want to charge into the back country, a TC is better. We prefer a trailer because we can leave it at the campsite quickly and easily, but there are disadvantages in rough terrain.
