Horrible design flaw Redhawk 25r

Hey everyone I have a 2018 redhawk 25r. Yesterday the cold water was scolding hot. I drain the hot water tank thinking that was the issue and shut it off. Today we go to shower and it’s blazing hot again. I finally get underneath the coach and notice the freshwater tank is about a inch above the catalytic converter. The exhaust is boiling my freshwater ugh!!!!! Great design Jayco. I’m on a 2 week cross country trip with my family. Sucks.

Yeah that would be a terrible engineering flaw. Is it possible to install a heat-shield?
If not the catalytic converter needs to be moved or the FW tank, which ever is feasible.
But contact Jayco or your dealer about the problem since it seems a warranty issue.

We just bought a 26d Entegra and the fresh water is super hot all the time after driving, I’ll have to look at ours too

The catalytic converter is usually right off the headers and I'm betting what you see is the muffler.



Find an auto parts store along your route that has a muffler shield kit like this:


Muffler Shield Kit | Design Engineering Inc


https://www.amazon.com/Design-Engine...ler+Shield+Kit



Crawl underneath or stop at any muffler shop and get it put it on.

Read the reviews on your link and noticed this:

Question: Can this be attached directly on to the muffler??
Answer: You can but do not use on RV. RVs seem to create more exhaust heat than normal. I put one on and it burned the lining of the rap. Did not work for me. Took it off

I did 30 seconds of searching to find that. If that particular one ain't perfect, find one that is designed for your specific application. They exist, aren't that expensive and generally easy to install.



If the OP thinks hot water is a problem, I can top that. My KTM dirt bike motor liked to boil the fuel in the fuel tank when ridden in warm/hot weather. You would think the bike manufacturer would have that figured out by now, right? I wound up finding some adhesive backed, volcanic rock coated film to use for my issue. Worked fine, no more boiling fuel.

! That's one way to get it done. It may actually be a welcome design in Alaska!
