Bought a while ago just in case my trailer gets stuck in an apartment somewhere. It happened and I had to change a wheel at the side of the road. sooo I do exactly what I'm supposed to do, roll my good wheel on it to get the wheel I need to change airborne. The problem was that ramp was too low and couldn't lift the wheel I had to change high enough. Long story short, I had to call my AAA to find a jack good enough to save me (I couldn't use a jack because that would be sketchy), so just a warning to others, don't get stuck stay like me. BE CAREFUL WHEN PURCHASING.
