Just my 2 cents worth: I own a 2005 Aspen Classic which I've towed (with a GL1800) thru numerous states, both flat and hilly and have many miles on it. The only mods I've done is to add a shore power outlet for electric service, changed out all the lights to LEDs and installed 5-spoke aluminum wheels with 5:30-12 tires. Well built and very roomy, especially since I travel alone. More room than anyone needs.

But - if I were to do it again I'd take a real hard look at the Roll-A-Home trailers or one of the other makes where the top of the trailer hinges down to become the floor of the dressing area. The tent of my Aspen (the dressing area) is directly on the ground under which I first put down a tarp as a ground cover. Invariably, the underside of the ground cover gets damp and covered with sand and dirt which must be swept or brushed off before folding up to use again the next night (a real pain in the axx to do). Some Aspen owners don't use a ground tarp and let the tent reside directly on the campground surface but then the bottom of the tent must be brushed off before final folding. Also, because the tent is directly on the ground I always spray around it's perimeter to keep ants out.

Anyway, that's the only gripe I've got. Like I say, if I had to do it over again I'd buy a camper where the top hinges over to become the floor of the dressing area which has to be easier and faster to fold up than what I currently go through. Just my 2 cents . . . .
