Upgrades for towing

I just bought a 2007(Classic) 2500HD with 65,000 miles on it. It is bone stock. We also just bought a 40' 5th wheel holiday trailer. Dry weight of trailer is 12,500lbs. What recommendations do you have for any reliable and useful modifications to accommodate this unit? This truck will only be used to tow the trailer, and will just sit in the driveway the rest of the time. Thank you in advance, Mike.

as long as everything is in good shape, the truck stock can pull that all day long. Upgrades are plentiful and expensive, probably time to start reading through the performance threads

Seems an EGR delete and a tow tune is in order. I was wondering about upgrading the turbo.

Don't touch the turbo unless your upgrading the trans as well, if you expect the vehicle to tow well and without introducing more variables/problems. Adding a turbo will not be good for a stock Allison especially if you're towing 13k

Egr delete is a thing, some people do some don't. It's more a longevity mod than anything. With a tow tune, it'll likely be turned off anyways. Add a $10 blocker for cheap insurance it won't open under boost, or delete it entirely for 50x more money.

Good advice, thank you. I'll do the $10.00 blocker and tune. Just leave it at that.

What benefits would I see from these upgrades Mr. jg358? I don't want to jeopardize any reliability issues.

They're about increasing reliability and longevity.

Pyro gauge (exhaust temp) lets you know when you need to back off the skinny pedal towing.
PCV re-route stops the PCV gasses from being circulated into your intake and clogging stuff up.
Block plate stops exhaust gasses from being circulated back into your intake.
Larger down pipe to replace the squished factory one will drop your EGTs
Exhaust will drop your EGTs.
Lift pump adds another water seperator and another fuel filter along with taking some strain off the CP3
EFI live is your tow tune. Not really a must but I really like my tow tune with turbo brake.

^^^ all good ideas.

My point was that as long as your truck is running right, it'll tow that stock all day long. All the listed upgrades are the ubiquitous ones and done for the sake of longevity and reliability.

What Jack said^. He's helped me with similar issues. I also tow a 12k+ fifth wheel and may I suggest an air bag system for the rear. I pull it as a goose neck though so its a little different. But it does help.

There are as many upgrades out there as you want to pay for. I would personally do a few things to pad the longevity factor. The last thing you want is to be stranded hours from home pulling that camper. A lift pump, blocker plates, and a tow tune would be my choice. An exhaust brake is a very good add for pulling weight.
