Re: Difference between the E-150 and E-250 Sportsmobile
Need more details. What year E150? Engine size? Newer E150s (2008+) are the same as older E250s, more or less, as they upped the weight rating, brakes, and other parts.
For a pre-2008, I'd seriously consider at least an E250 if you want to tow anything. Even without towing, the weight of a camper build-out can quickly overwhelm an E150, and that's before you even start loading it up for a trip.
