Non-level campsites Class A

The blocks I built where for Dad's trailer. He had made some (I re-used the boards) He had laid out the holes, drove inch long screws drove halfway in and then holes for the heads to fit in. They bothered me because I know boards split, and wood screws, with their points, can flatten a tire. The carriage bolts, if split out of wood will have a round head on 1 end, and a nut on the other. If it does go thru a tire, tire is ruined, but the ends are large enough not likely to stick in tread.

Yes, I know all too well how boards can split, and how the sharp pointy side of a wood screw could flatten a tire. I thought about that a lot, when I was figuring out how to build these boards/ramps several years ago.

That was why I made sure all wood screws holding it together have pretty large, flat heads, and are pointing DOWN. Also, they are all located near the outside edges of the boards. This way, even if a board cracks, its very, very unlikely a screw would find its way into a tire.

Been using these boards for several years with two different Motorhomes now, never had a problem yet. Welll, except for the groaning and complaining I get from teenage kids whenever I ask them to help me get them out, and put them away when we leave. :)

.... Another idea would be sandwich rubber belt (Mud flap?) between the bottom 2 layers, with a tongue sticking out long enough to be under the tire before it hits the ramp. This would make sure they did not slide as you pull on.

Hey, I like that idea! Sometimes I do have a problem with the board sliding out when driving up onto it. Rubber flap sandwiched in like you describe here would definitely fix that problem. Just might have to look into doing that.
