Ramp Door Reinforcement

[TWZMYJP]

I'm looking for ideas on ways to add some strength to our ramp door. We primarily use our toy hauler for our Jeep, and it puts a pretty good strain on the ramp door when we load it. I am currently using old timber planks to spread the load, but it's cumbersome and just something I'd like to do away with. My thoughts would be some sort of flip down jacks or supports that mount in the center span of the door, and can be adjusted for uneven terrain when the ramp is deployed for loading. I don't want to put anything on the top/inside of the ramp, as that would become a tripping hazard when we have it setup as the elevated patio... Anyhow, just looking for ideas or input from anyone that has done something similar? Thanks in advance!

I like the idea of some additional structural ribs on the outside of the ramp. Also gives a way to attach a bracket for a scissor jack or something in the middle of the span. Thanks for the input!

Rather than channel, box tube would be stronger. Maybe 1-1/2" square. But you have to drill access holes for installing the nuts to bolt them to the ramp. Use grade 5 or 8 bolts for a smaller size bolt and nut, but fender washers on the bolt head. I'd use two in the area of each tire path. You can also use temp blocks in the center of the ramp.

Do the trailer floor while you are at it.

I would use two 4X6 blocks to support mid span on the sides plus an assortment of 2X4s to make them work/support near the mid point.

It will be interesting to see what advice you get. Having seen how little structure there is to these doors, I'm surprised you haven't broken it yet. I think most only have a 1000 or 2000lb weight limit.
