We purchased this to get ready for our latest camping trip across the southwest states. Fortunately, we did not need to use it for our travel trailer during our recent trip. However we did use it to assist another couple who had a tire on their trailer that was totally shredded. He did not have any kind of Jack to be able to change his tire. This worked amazingly well, so much so that he asked for the link so he could order one from Amazon too.

Effective Tool

Color: Yellow, Size: 5.5" Lift

Go try to use your standard car jack to lift your two axle travel trailer and see why this simple ramp just works. I have used this ramp for changing trailer tires, packing bearings, and changing brakes. It's effective in lifting one tire even though the suspension is articulating. It is also much more stable than a hydraulic jack under an axle. I highly recommend this ramp for travel trailer use.
