Stay away from rear kitchens. Get the largest grey water tank you can find. Look at the wheels, if it only has five lug bolts, don't even go inside. I have had some experience with the Chinese tires on a boat trailer, they came apart sitting in a storage building. But the tire failure problem is by no means limited to foriegn made tires. I have scattered tire treads in several states from at least five different domestic manufacturers. Try to find what you can be happy with that has a loaded weight that is not anywhere near the carrying capacity of the tires. For me, 30' would be the ideal length but most manufacturers aren't making them that size anymore. I currently have a Newmar American Star. I ordered the trailer with easy lube axles and dish ready, I got suspension with greasable spring hangers and a piece of wire sticking out of the roof for a satellite dish. Find out the height of the unit, it could be critical later on looking for storage, etc. If I were in the market right now I would look hard at the KZ New Vision and the Titanium. The four seasons insulation is a must as is the insulated underbelly. If you are in Kansas City area, go over to northern Indiana and visit some of the factories, most will take you inside and let you see the building in progress, very enlightning. Actually buying a less expensive used unit and using it a while is invaluable experience before buying a new unit. Happy camping. bg
