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.

*Perfect* small camper hose for water filling
Size: 50-Foot, Style: Expandable Fabric
Well designed and very functional! Even if you have a small camper like a teardrop, I encourage you to get a longer length hose (minimally 50 ft).
It really is drinking water quality hosing. I hate the weird plastic-y taste that you get from a standard yard hose. When I fill up the tank on my camper, I want water that tastes good, not like plastic--and this hose delivers. ZERO plastic flavoring! For pulling water from my house spigot, we can directly fill our water tank with zero issues. When we fill from well water or other sources on the road, we also add a water filter to the mix.
I love that this comes with a mesh fabric holding bag to keep the hose stored safely and cleanly, while still allowing it to dry completely. The bag is large enough to actually accommodate the hose easily (although warning, it can be challenging to roll up this much hose without having the center fall out... pay attention when doing it, or better, do it on a flat surface before transferring it to the bag).
I originally bought a 25 foot hose. That was a mistake. The 50 foot does not take up much more space in storage, but it is so much easier to work with when running from a spigot to your rig. I now have both a 25 ft and the 50 ft--and we bring both with us when on the road. There have been several times when we have needed all of the length of those two hoses connected. Sometimes you need to fill up at a gas station or rest area where it can be hard to either get your rig close enough, or when there are other vehicles blocking access. Having the extra length gives you options.
The hose does not kink in use. At least, we have never had a problem with that happening. Mind you, we only roll it out straight to our camper, so it's not like I'm dragging it around the yard to water plants. Additionally, this is a remarkably lightweight hose, making it easy to move around.
While not the cheapest, this is compact, easy to store, and it does its job perfectly, making it a very good value for the money.
