Would you do it?

Pairing a 2021 GMC Sierra 2500 HD 6.6 gas and a Grand Design Reflection 320MKS.

Trailer is 10495 dry, 13995 GVWR and a dry pin weight of 2040. Truck GVWR 10450, GCWR 24000, RGAWR 6390, Curb 7078. Max payload 3372.
Fifth Wheel tow max 16650 and max pin of 2490.

The only issue I am seeing is the possibility of fully load being over the pin weight by 2-300 lbs if not loaded properly. Probably use a Anderson hitch to keep the weight down.

Anything I'm missing? I'm not looking for the get a 3500 comments, I'm asking if I'm missing anything that looks out of line besides being close on the pin weight. Thanks in advance.

Have you considered your rear axle ratio...many are standard 3.73
We factory ordered a 4.30 (teamed with a 6.2 Ford gaser and 6 spd transmission.
Never regretted it.

20% of 14,000 max GVW for the RV translates into 2800 pin wt. 20%of 13,000 translates into 2600 pin wt. Go from there.

Looks as tho the OP has already made his decision and just looking for others to agree.
Sorry won't get agreement from me.

If you don't make financial sense with major purchases you may find yourself watching the repo guy tow your toy away. I make sense with every major purchase and pay cash. That doesn't mean you can't have toys.

WE are not talking about buying something you can't afford.
This is not a repo man issue. We are talking about the right tool for the job. Several have commented that the combo is not a good match.
That's all the advise any of us can give. It's up to you to listen to the advise.
For the most part you can always use a smaller hammer, however using the smaller hammer takes twice the effort when the job requires a big hammer.
When driving requires too much effort the trip is less than enjoyable/relaxed. This advise is coming from someone that has experienced the pitfalls of towing with a marginally adequate truck. It's no fun! It's not enjoyable.....but you will get there...eventually

I know the loaded and unloaded weight of the present trailer, took the difference which gives the content weight, added the difference in water capacity, propane is the same, added 300lbs more just for the sake of argument. The trailer has the actual weight leaving the factory. So no its not exact but everything going in has already been weighed in our current 35ft bumper pull.

our loaded weight is 12387

If you know the loaded weight...did you get the various axle and pin weights when you weighed it?

No need to put up red herring numbers about empty weights if you have travel ready reality.

Now, is 12387:
- What the scale showed for the axles or after you calculated the total weight including pin?
- Was that including propane and full water tanks?
- What are the axle weights for the truck loaded to go?

I would expect the pin weight to be on the order of 2,500-3,100...add in hitch and two people and you are basically at your payload without anything else in the truck.

Camperforlife has correctly said the gas vs. diesel money issues have changed with the significant diesel up charges and the diesel per gallon costs.

[Campinghoss]

To answer your question directly, no I would not do it and I didn't do it when I purchased the fiver in my sig. I had a F-250 diesel and due to weight I upgraded.

[Super_Dave]

We bought the truck before buying the trailer and didn't want to be constrained when we bought the trailer so we bought the biggest truck that we could afford. As the guy driving, I also don't want to feel butt clinched when I'm supposed to be on vacation having a fun/relaxing time. IMO, overkill in the tow vehicle is well worth all the upcharge of a diesel. When I start trying to make financial sense out of my toy purchases it is time to quit.

GM just shows a 6390 rawr with 17" wheels or 6600 rawr with 18" for their 2500 trucks.
I would say his 7078 rawr number is a typo.
If its the 6390 rawr 17" wheels your gonna' have a maxed out rear suspension with a 14000 gvwr trailer once its loaded and road ready.

The question was "would you do it" ?
The 6.6 will be marginal for that much weight ....so no, for my use I wouldn't do it.
From what Ive read the 6.6 gas pulling those kinds of loads isn't getting anywhere near the mpg as the 6.6 Dmax pulling the same load and especially mpg's running empty.
Just my 2c.

7078 rawr number is a typo, that is curb weight and has been corrected. The 14000 is no where near what the actual weight of the trailer. The dry weight is 10495, our loaded weight is 12387

You are probably pushing the limits on the overall payload also.

Why are you getting a new truck but purposely getting one not suited to the expected use?

My thought as well. Get Bigger truck, bigger engine. Get a truck that will do the job vs. a truck that will be barely adequate.

This is why we went with an F350 vs the 250. The payload was just too close on the 250. I'd rather have room to spare, not only for safety but if you decide to buy a bigger FW later then you have to buy both all over again.

While most would not consider that rig matchup to be ideal, it is certainly do able. With a GCWR of 24,000, GM is saying the drivetrain is capable. You will need to stay within RAWR/tire rating. At full FW GVWR, that may be close. At the gross wt you listed in your recent post, likely no problem.

The new GM 2500 HD is a stout truck, almost a 3500 in capability and higher than normal class 2 ratings.

Nothing wrong with the Andersen hitch, if that is what you want. Another good option is the 3700 for GM oem puck system. It is not too heavy, and manageable for one person in/out, as it easily separates in two pieces.

I don't see a real problem in your choice!
