Tire Ramp for Easier Water Tank Filling

March 20, 20142

The first couple of times I filled my water tank, it didn’t last as long as I had expected. I finally realized that it wasn’t actually getting “full” because water was running back out the fill hose unnecessarily. To combat the problem, I created a small ramp for one wheel to sit on which helps angle the tank for proper filling.

The concept is quite simple really – I just purchased some thin wood, cut into different increments, and screwed them together in a ramp form. I then back the trailer onto the top, as shown by the image above.

One tire lifted for easier water filling on your popup camper

This results in my camper sitting slightly elevated at the water inlet side, which means the water doesn’t accidentally flow back out the inlet, but completely fills the tank. I feel this gives me about 2 additional gallons of water, to be truly “full.”

Don’t want to build the wooden model I use? Try this plastic Tri-Leveler from Camco, which also works for leveling your camper if you don’t want to use my recommended BAL leveling jack method.

Extra Credit

I place this ramp on the opposite wheel to truly empty my water tank, tilting everything toward the drain spout.

I've been camping regularly since I was a kid, from quick Cub/Boy Scout trips to week-long backpacking trips and everything else in-between. We got a popup camper when our kids were 1 and 3 years old to enjoy more time outdoors together alongside a few conveniences like heat and running water. Since then, we've spent over 75 nights together as a family in our popup camper. I've learned a lot about the intricacies of a popup tent camper during this time and love to share those lessons here for the benefit of others.
