Well,I went and did it,got myself into a 1998 Viking 2490 popup camper! Box is 12 ft close up and tows like its not even there. Dry weight is 1880 lbs with a cargo capacity of 800 lbs! My Mountaineer handles it very well. Does need a few improvements. Going to add solar ,increase water capacity to make it off grid. A little TLC and it's ready for anything.
