E-21 Kitchen water supply lines (classic)

I think Scamp and Casita did it right by keeping the water supply lines inside the trailer. It really makes it easier to camp in colder weather and extend your camping season with inside water supply lines. Escape's 21 outside water supply routing also results with four holes drilled through the floor, 4-6 extra PEX fittings, and 8-12 extra crimps. A home run of PEX from the kitchen faucet around the inside rear of the trailer to the other plumbing may use more PEX tubing but cost would be offset in material, reliability and possible labor savings. Also the current PEX routing also make it really difficult to isolate the outside exposed water supply lines for winter camping. I feel Escape needs to reevaluate their water supply plumbing routing if they have not done so in the newer models. Before I get jumped on, this is just a concern and product improvement suggestion.

You left out the biggest issue for me with the 21 kitchen faucet PEX tubing. It's exposed to UV! PEX should never be run where it is exposed to UV as it will cause the PEX tubing to break down and fail.

Escape doesn't claim to be a 4 season trailer. While it would be possible to run the water lines in a 21 inside the trailer, the run from the water heater to the kitchen (running across the back of the trailer) would be long enough that one would waste a lot of water waiting for the hot water to reach the faucet. Not so good for boondocking.

Redesigning the trailer so the water heater was located under the passenger rear bench seat might work, but that would require wider bench seats, and a long run to the shower/bathroom sink. All is a compromise...

As to UV, not much direct sun hits the lines in my 21.

I put pipe insulation around the outside pex lines. I used a large diameter tube and wrapped it around both the cold and hot lines. That way the hot water in one line would help keep the other from freezing. I also wrapped the elbows with saran wrap and then sprayed some expandable foam on them. No uv and additional protection from freezing.

UV damage doesn't require direct sun - indirect (reflected) UV will damage PEX as well. Think about it - can you sunburn on the beach under an umbrella? UV can bounce off pavement and damage the tubing. A covering of pipe insulation on the exposed PEX is good idea.

Or carry a couple of sections of PEX, fittings and a crimper for when the PEX bursts.

Oh, I carry so much what-if stuff, I really can't face adding more to my traveling spare parts supply. I'm glad I have a 19 so the lines are inside, but maybe I will feel different if any PEX fails.

As long as we're making suggestions... a possible routing of the lines which cross the trailer would be at the step in the floor. The pipes would be on the inside of the shell, just in front of the step, from the cabinet under the refrigerator to the cabinet under the sink. The raised rear (dinette) floor would be extended forward just enough to cover them. A toe kick panel (or think of it as a stair riser panel) would finish off the front side, preferably vented so the space would run closer to interior temperature than exterior.

The 5.0TA has the same layout as the 21' in this area, and presumably the same exterior water lines; the same solution would work.

I would have the water lines outside the shell in case of a leak....

water lines

Now you're all making me like our little 17B even more. We never had a problem with the 19 or 21 water lines but the 17B has the pump, water heater, kitchen sink and bath all in line and close. Of course there are other advantages, Nancy doesn't take a vacuum along, something about not enough floor to need one.
