I tightened and checked everything on my Aliner 12 before I took my trip. I bent both of my 2000lbs axle pins, which caused the inner tires to wear quickly on both sides. I went through 4 sets of tires, and resorted to flipping the rim, during the last 500 miles just to make it home, although it didn't exactly fit with the tapered lugs and wheel hubs. I bought new steel wheels and they are both now out of round. I collected a dozen square head screws that came out from somewhere?! My Blue Sea voltmeter that was mounted on my battery box, which heated high enough in CO to melt the battery box. 2 of the long front body to frame screws backed out or quit holding. The propane heater vent pipe backed out and was damaged beyond repair. The front roof is not aligned straight. It favors the right side, which caused the inside to rub on the outside of the aluminum on the rear roof. My new AC stopped working after a week (something was rattling loose inside) I had a canadian field mouse crawl up my power cord, and enter my camper at 3am to eat my trash. I bent a perfectly good frying pan trying to kill it while it crossed over my legs. My fantastic fan started to leak, and the top looked sealed, so I recaulked the 4 inside, corner screws and it stopped. My new Duracell deep cycle battery would not make it through the night, so like clock work, the smoke detector would beep a couple of times and then stop. I noticed that the battery would not charge when the ambient temperatures were high. The sink top and AC counter both became loose and had to be resecured. When I fold the sides, the point of the top triangle rubs badly on the center divider of the window. The table top became detached a couple of times and had to be resecured. Went through a couple brake lights. The good news is that I hit a hail storm and just missed a tornado. Having said all of this, I still love the camper and am keeping it. You just can't beat the quick set up of an Aliner. It kept me warm in 30 degree temperatures and 90 degree days, when the AC was working. I could be sleeping/napping in 20 seconds after a long days drive. I only saw one Aliner during my entire trip. I just installed a 3500lbs Dexter axle with electric brakes with a 32 degree down. Adding 14 inch aluminum wheels.
