I am on my second Weekender Camper. I purchased a new 1010 in 1996 and now I have a used 1995 910. The dry weight posted on my 910 says 2,750. Mtnman is correct on the weight issue there. I'm sure mine now weighs closer to 4,000 fully loaded and wet (full water tank, fridge, supplies, etc.) My 1996 Chevy Silverado dually handles it just fine with no modifications. The 1996 1010 I had rode on a 1992 GMC dually also with no problems for many, many, thousands of trouble free miles.) As for the build quality, they are really no worse than any other. I would assume at this point any major issues that came with it have been corrected or worked on. I just replaced the roof on mine. Big $$$ so do make sure that is not an issue if it's been replaced as the current owner says. Yes, there is particle board cabinet doors with "oak paper" on them,(mine is peeling on a few) as well as areas with staples, etc., but all in all I LOVE my Weekender for a number of reasons. First, the cabover has metal straps that start underneath back at the cab and go all the way up and over to the back to avoid "cabover sag". This was an important feature for me when I bought the new 1010 and now the used 910, as the extended cabover can be weighty on these beasts. I LOVE, LOVE, LOVE the full 7' ceiling height. the central furnace with the duct in the bathroom is really nice, all the holding tanks are insulated and heated (when the furnace is on) and it has a TON of storage. The only drawback I've ever had with the layout is the small area for your knees in the bathroom.... Other than that it is well insulated (I've camped in sub-freezing weather in mine) and a "pretty camper" with a lot of little extras you don't find in lower end campers; at least not at the time they were new. One thing I would make absolute sure of is the jack mounts. Was it sitting on the jacks in the air? If so and the bath wall was "bowed" that could be a sign of frame fatigue, so be careful there; especially if you intend to camp with it off the truck. However, if it IS sitting on the jacks and is solid up in the air, no leaning jacks etc., and you can go in it with no issues that's a GOOD sign. A lot of the older BIG campers like this on are prone to the rear overhang sagging over time. If you have any specific questions feel free to PM me. I know my camper like the back of my hand and have the original brochure, etc. Good luck!!
