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.

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.

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

We tow with our 2008 Chevy 2500HD Duramax truck, and have never had any issue with excess heat damaging our fifth wheel - and we have towed our trailer many miles.
Is your exhaust pipe the OEM standard, or did maybe someone change it at some point? Our OEM standard pipe has an opening about 2 feet from the rear of the pipe that sucks in cool air and cools the exhaust. Does yours have that opening?

I am so glad my 2003 Duramax doesn't have that Regen problem. Have you noticed the huge increase in semi fires? That's why. My company lost several trucks to it. I will go back to gas if I ever replace it. The problem is some of the extra fuel forms droplets in the exhaust. It will not ignite until it leaves the pipe. So it is burning when it hits the trailer. It is not working right when that happens. But it won't normally cause a check engine light. When you get behind a truck in Regen and it's like breathing kerosene that's what is happening. And that's why they catch fire.

You could get a bolt on tip that is a little longer so the exhaust would go out past your trailer (and can take it off when not towing

Yup, it is still the OEM exhaust. I've owned the truck from day one so I know nothing has been changed. I've got enough room between the trailer and the truck I can get my tailgate completely down and have a few inches to spare.

I'm pulling a 2017 Seismic 4114 with a 2016 3500 Dually DMax . This camper sits much closer than my 2015 375BHFS because of the shorter over hang and it is 6" wider. I haven't notice any problems with either camper. I also have never seen the regen light come on in my truck for the last 40,000 miles. I find it hard to believe there's enough heat to do damage while going down the road unless there is something wrong with the truck. There's an awful lot of cool air rushing by between the exhaust tip and the front camper wall.

There is no regen light. The only way you will know it’s in regen is the rpms will be about 300 higher at idle. A typical LML will regen once per tank of fuel, I think GM states 450 to 550 miles.
With exhaust gas temps in the 1400* range I don’t think there is enough cool air in the stale area between truck and front of 5th wheel to cool it.
I haven’t experienced any melting issues YET, but I have only been on 1 trip that I know my truck went into regen on (just purchased truck this year). This is something that I am concerned about myself, guess time will tell.

I'll post up a pic of what its doing/done.
I got an idea for a easy removable heat shield for that front corner of the coach.

Consider buying a 99-03 Ford Super Duty with the Navistar 7.3 diesel.

If your egt(pyrometer) temps before turbo exceed 1150 degrees Fahrenheit, it is close to piston meltdown time.

Maybe check with a muffler shop to see how they
could add a chrome deflector pipe at the end of your
existing tail pipe that deflects the heat away from the
trailer. They also could install heat deflecting pads
around end of tail pipe.
