We have a Scamp
5er that's been substantially remodeled inside, weighs about 3200lbs fully loaded (clothes, food, propane
, water, etc), and we've hauled it all over the western US and some of Canada (Vancouver Island, BC, Grand Canyon, Yellowstone, Utah, and all over Washington and Oregon) using a heavily-used former fleet vehicle 3.0L V6 Ford Ranger we bought after it was repossessed . . . about 15,000 miles all told.
Fair is fair: we did have to rebuild the transmission after hauling our trailer around for about 15,000 miles, but I'd been worrying about the tranny since we bought the thing, so I wasn't overly surprised. I added a transmission cooler (which I should have done before the tranny failed) when I had the rebuild done.
The point is you don't need a lot of truck to pull a Scamp
5er, you get good gas mileage, and its very easy and comfortable to drive.
If you're small of stature, the Scamp
factory floorplans work well for families of up to six. If you're a couple out on your own, a remodeled Scamp that has a Front-Back Queen-size bed in the loft is a wonderful thing, but you cut the sleeping capacity to the couple in the loft and two kids in the dinette.
