I finally have both a little time and $$ and want to visit so many cities and burbs. Need RV suggestions. I have narrowed it down to class C. Need to sleep 5 ( tight is ok). Thinking overhead cab for 2, back end, 2...and dinette 1. 24-25 ft too park on a city street if necessary. Been looking at benz van or transit front. However, a rig that tows a 6,000 lb 28 ft, trailer and boat dry, would be a cherry on top. Is there such a beast? Chevy van front with a 8.1 496??? Am I making shit up?
