Thanks for the replies so far. I don't think I'll ever hit the max towing capacity of the PW with what I've got. Mopar says the towing capacity of my 2019 is 10,350 lbs. The dry weight of the trailer is 7,688 and it has a max carrying capacity of 2,012. So I'd max out the weight on the trailer (9,700 lbs) before I hit the max towing capacity of the truck. Given that I have air bags as well, I think I'm okay weight wise. I was mainly wondering about reliability, gas mileage, and anything else I may consider. I also definitely realize it will take a lot of miles to make up the gas mileage difference when compared to the up front premium you pay for the diesel engine.
While it sounds like you won't have an issue, the big thing you have to remember is that you'll run out of PAYLOAD before you run out of towing capacity, especially with a camper.
Think of it like this:
Your tow rating is, in essence, an abstract number, chosen based on what your driveline can safely get moving and stop.
Your payload is how much weight you can add to the truck, driven by your suspension, the weight of the truck, and a somewhat arbitrary set of guidelines.
Your Gross Axle Weight Ratings are how much weight each axle can handle, driven by what axle is under the truck and your springs. These are CONCRETE numbers that you don't want to go over.
Here's where you will find your issues, and why a lot of guys on here will tell you the safest way to tow is to go get weighed as if you're ready for a trip: You HAVE to pay attention to not just the weight of the trailer, but how much tongue weight it has. And if you're using a WDH, then you need to look at how it is shifting the weight back to the trailer and back to the front axle of your truck. If that puts you over your GAWR for EITHER axle, then you are asking for some troubles. If it puts you over your payload, you *may* be okay.
It's also why you can pull a MUCH heavier boat than you can a camper - MOST (up to a certain point) boats have the weight primarily carried by their trailer axles, and have very little tongue weight. This means the weight your truck is seeing is relatively small.
But when it comes to a camper, a much larger percentage of the weight ends up on the tongue - and thus on your truck. It's why you can see a 8k GVW trailer advertised with almost 1k lbs of tongue weight, while an 8k boat on a trailer might only have 500 lbs of tongue weight.
Really all this is food for thought. If you're paying attention and realize that, as a PW, the truck has limits much lower than that of a standard 2500, then you'll likely be fine.
