Trailer meltdown...

My Duramax exhaust gets so hot its warping the trim material on the lower front right corner of my Northpoint. This is mainly happening while going down the road. When its parked I dont let it idle long while coupled up and if it does I turn the truck to the left a little bit so the exhaust is pointing away from the trailer in case it goes into regen mode. I'm sure others out there with a Northpoint, Pinnacle or even a traveltrailer that sits low have to be experiencing this issue.

So what have you guys done to prevent this?

What year is your Duramax? I'll hazard a guess that the serious heat is from the regeneration cycle. If so, maybe you could force a regeneration when you are not towing.

Hopefully you'll hear from others in a similar situation for a better solution.

Get yourself something like this.

https://www.amazon.com/MBRP-Exhaust-.../dp/B000OAW2R0

They are ugly as sin, but will keep that heat going down instead of strait back at your trailer. I'm not sure of the size of your Duramax exhaust at that OEM tip. You may have to cut it off and add a turndown back on the pipe itself to give yourself some clearance.

Again, just verify your pipe size. I have no Idea if the one I linked will fit.

I did kind of think about that, but with my luck I'd melt the front cap of my 5th wheel. Lol!

I did think of one of those too, and your right they are ugly as sin. I just cant force myself to install one of those.

My BIL has a Duramax GMC, and I saw how the exhaust was pointed. I think this the first post I've noticed on this, so not sure how common a problem it is. I do know there's a bunch of folks here, that tow with them.
My guess is you'll have to deflect the exhaust away from the camper, one way or another. And attaching a heat shield to the camper would REALLY be ugly!

I use the "Rock Star" mudflap and it has a metal plate on the back for heat. Also works great on blocking rocks and debris for it is 1/2" thick and doesn't sail.

Saw this on the Duramax forum. Not cheap.

Here’s the heat shielding on my PSD. Never had any concerns before or after adding the mud guard.
