A Must-have for Double-axle Travel Trailers
Color: Yellow, Size: 5.5" Lift
I moved from a diesel pusher motorhome back to a truck and Lance travel trailer. ‘Done with Diesels’ is my new motto. I wanted to check the wheel bearings and couldn’t find the proper way to jack up the side. Some people said jack here, some said jack there, and some said never to use a jack at all, so I was confused. Decided to use some of my leveling blocks and build a ramp to drive up onto and that ended in failure. Either it wouldn’t go up without spitting it out and still wasn’t high enough. I resorted to jacking it up at the spot I thought was best, but wasn’t comfortable with the entire side supported with a small bottle jack cylinder. So I ordered this and it was well worth the wait. Trailer pulls right up onto it and the other tire is ready to work on. The weight is more evenly distributed and certainly feels safer. Obviously this won’t work for a single axle, but for double axles it works for maintenance and makes tire changing a breeze. It’s as good as everyone says it is and has a permanent place in my trailer storage compartment.

Works exactly as stated with a dual axel trailer
Color: Yellow, Size: 5.5" Lift
I purchased this on a hope, I had a trip planned to pull a school trailer 2600 miles round trip and had to use my pickup truck jack if I had a tire issue. I didn't like my odds and bought this ramp hoping it would make things simpler. My second day into driving and I had my first tire blow out. The ramp workers perfectly and I had the new tire on the trailer in 15 minutes. Later in the day, I caught a second tire on the trailer down to threads and used the ramp again to change out tires at a truck stop. I analyzed all the "whys" as to what made the tires blow and fixed it to make the rest of my trip safe and trouble free but this ramp made things quick and easy when i needed it. I'd totally recommend this product and I'm planning to purchase another and leave it with the school trailers for future use. Keep in mind you need at least a dual axel trailer for this to work and have a spare tire to swap to.

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.
