Bunch of Questions!

You have to ask yourself "Do I want a good solid frost resistant camper with double windows and good insulation?" Then ask yourself "How much can I afford?" Often it seems people want a lot more than the truck will handle, however there is ways to make the wheels and tires and the suspension carry more than the posted GVW. Best thing to do is have a look in the forum for heavy and weigh and GVW and see what people carry and how they modify their truck to do it safer than the OEM that the truck came off the factory with.
