tow with a Cl B MH all the time
A MH van may be the best trlr tow vehicle. Enroute, U can sleep in MH & not disturb/set up the trlr. I don't have A/S as my acct shows, but I took my 34' Featherlite from Gulf to Glacier NP with 1997 Coach House MH in 2012. No problems at all via NM, CO, WY Big Horn mtns., MT, ND, MN, IA, MO, TN, AL. High alt. cuts power, but heavy MH aids stability. CH is on an E250 extended HD chassis w/E350 rear springs.
Let's Roll !
PS: I can power trlr w/MH genset !
