I have a 84 Allegro w/454 eng..Has anyone towed a full size van with this MH ? We go to Florida in the winter and would like to take our Van with us..I can get a used Demco tow dolly rated at 4800 lbs and am unsure if this would be big enough..The van placard says 3400# on front and 3400# on rear..Can anyone give us a suggestion ???
