DIY Storage Ramp for Leveling Trailer?

[southpaw]

I have been searching around this and various forums to see if I can find some help and/or plans for building a ramp for my trailer. Basically I have an angled driveway and want to build a ramp that I can park my trailer on when parked at home that has storage underneath.

The specifics of driveway angle, trailer weight, and other details I know are crucial for determining design specifics for materials etc. I was putting this out there in the hopes that someone had taken on this project before and might have a design that I could use as a foundation for my ramp.

Outdoor deck forums and articles have been helpful but a design specific to a trailer would really help.

Thanks in advance,

Greg

I restored my entire trailer on such a ramp. You can see various pics of it in my thread here vintageshasta.proboards.com/index.cgi?board=yourshastaphotos&action=display&thread=147 The trailer was on there for over a year. I wished I had built the ramps wider, it was pretty hard getting the traielr on it becasue the alignment had to be spot on, but once it was up there it was solid a as rock. 2x8 frame with 1/2" plywood on each side. I used Simpson Titen concrete screws through my driveway to hold it from slidng down the hill.
