I'm just getting into van camping and I've got a question for those who have the experience. I see all these different builds for beds out of wood. That seems like it would add a lot of weight. Wouldn't it be simpler to go with a metal frame? Granted you may have to cut it down and weld it back together and you'd most like have to add to the legs but it seems it would be lighter, an easier build and potentially cheaper with what places like Big Lots sells the single frame for. Any comments would be appreciated before I get too far down that road.
