Recently, I wanted to examine the various systems underneath our 2011 Keystone Cougar 267RLSWE fifth-wheel trailer. I removed the coroplast underbelly for maintenance and a thorough inspection. In this video, a look at what I found and explanations of the various systems hiding under there.

I’ve settled into an RV park for a month to tackle some maintenance on my RV. I started by stripping off the entire underbelly material, which is a kind of corrugated cardboard, to expose everything beneath the RV for some much-needed work.

I’ve been focusing on reinforcing my water tank with plywood and angle iron since it had begun to sag. I’ve also upgraded some parts, like replacing the water pump and fixing rodent damage to the hoses. While exploring the systems, I noticed the wiring for the tank monitors and the setup for my bike rack which I’ve temporarily pulled out for access. The underbelly area revealed the complexity of the plumbing and electrical systems, including the water tank’s support, the slide-out mechanisms, and the brake wiring which I’ve recently upgraded with marine-grade wire.

I’ve also shown you the modifications I’ve made to the waste systems, including adapting the galley tank’s plumbing and installing electric valves for better control. The propane system, particularly around the water heater and furnace, was another focus, ensuring all connections were secure.

The RV’s underbelly isn’t just for mechanics; it’s also about comfort. I’ve looked into how the heating system keeps the floors warm, which is crucial when camping in colder conditions. There’s also maintenance on the black and gray water tanks, where I’ve had to deal with clogs and cracks using G-Flex epoxy for repairs.

If you’re curious about what goes on beneath your RV or if you’re thinking about tackling similar projects, stay tuned for more updates as I continue this journey.
