Great product!
Color: Yellow, Size: 5.5" Lift, Color: Yellow, Size: 5.5" Lift
This is the best product to own if you need to change a tire on a tandem boat trailer. We have never changed a tire on our trailer before so we did some research and discovered this product. It was the best investment made. Changing the tire was fast and easy.

An RV Must Have
Color: Yellow, Size: 5.5" Lift
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.
