I'm curious if this is unrealistic or not. Looking at options for a tow vehicle for a motorhome. I have a Ford F150 that weighs about 5500 lbs. and wondering if its too heavy a 30-32 foot gas motorhome to pull. (And that's with nothing in it. Would be nice to load up the bed of the truck.) I know it depends on the GVWR of the rig, but not really knowing what I'll end up buying, I'm just curious if this could be doable or not. I'm sure a diesel pusher would have a much easier time, but is it even worth considering with a gas unit?
