Curious what camp tables you use, other than tailgates! I can't remember the brand of the one I use but it rolls up and has four legs and two cross pieces that roll up with it. You screw the legs in. Great top but the legs are a little wobbly.

I use to have a picnic table that was made out of one sheet of 3/4 plywood. There was a parttern you layed out on the sheet and cut into pieces that fit into a table using nothing else. The table was 4ft long and stable. When done it came apart and lay flat. Kind of old school but this is the link..
