Hi I have just joined this forum , I’ve always admired theses Motorhomes. I have been researching on here and other places to better understand the vehicle before I buy one . Something that keeps coming up is that you can’t drive theses over 55 or 60 that the motors can’t take it ? I then read other claims it the hot rod of rvs . Which is it . I currently have a Ford e350 chinook and fully loaded I can do 80 ... not the best on mileage but no problem for the motor and rides fine.
