Changes to the 310RL weights and pin weight.

Looking at 2024 310 and noticed the GVWR is 15,000 vs the 16,000 on the 2025. What changed to make the weights go up in 2025?

Dry weights vary on the model. Some saying 13k plus. The one I’m looking at has a dry weight of 12,476, 2,522 pin. No gen, no wash/dryer. No plans for one either

I have a 2024 F350 srw, HO 6.7 and 12,000 gvwr. 7000 rawr (8000 on the tires).

Trying to make sure I’m good for a 310. Lots of posts on here I have read from people with a 310 and pin weights over 3000. Some towing with a 3/4 ton.

One video says the stuff you add to the rv adds 30% to the pin weight?

Another says 20% of rv weight is your pin weight estimation.

Only way to know for certain is to put on scale but it’s too late then. The rv would already have been purchased.

I think I’ll be good but wanted some extra input. Thoughts

You will get lots of different answers. We have a 2024 310 and pull with f350 dually. I weighed and had 7400 on rear axle but we live in ours. Maybe the 16000 is because it has upgraded suspension with H rated tires. Somebody on here will know. We have no washer or dryer and no generator.

Whats your pin weight? Being a dually your rear axle weight starts heavier than mine 3800.

My truck is 8800 loaded up to tow. ( b and w slider hitch, fuel, tools, us etc). That leaves us 3200 and we’re at the 12000 limit

I did not disconnect and reweigh truck. Rough estimate was at least 3000. There are others on here who can give you exact pin weight for their 310. My dually axle gross rating is 9900 pounds I believe..

Our 2025, built 8/24, has a GVWR of 15,000. Wonder what Alliance changed to allow the increase in GVWR to 16,000 and when did it change?

We tow with a 2020 F350 SCrew SRW, 6.7l, 11,500 GVWR, 7,230 GAWR and 30,000 GCWR. We are fulltimers. Our 310RL has a UVW of 12,952 and rides on load range G tires. No washer/dryer, generator or super solar. We exchanged the glass shower door for a Nautilus and all three barn doors for blackout curtains on rods losing 150 pounds in the process. (And gained in comfort and functionality in our opinion.)

We CAT scaled our rig when we headed south last fall. Fully fueled and both of us in the cab weighed in at 25,140 GCW, 7,320 rear and 12,900 on the trailer axles. Then parked the 310 and ran across with just the truck resulting in 8,900 gross weight and 3,760 rear. With the truck alone, our front axle increased by 120 pounds. The pin weight calculates out to just over 22% of the trailer’s loaded weight, right in the middle of the 20-25% range normally used as an estimate.

We have towed with this combo for just under 6k miles. The truck’s rear axle is definitely on the overloads. I’m thinking of bagging to help the ride. It seems to handle OK otherwise.

We also had some chucking last year that all but disappeared when I tightened up the B&W clamps in the puck holes.

Most of the storage in a 310RL is forward of the trailer axles so more stuff equals more pin weight unless you load the TV pantry and under the jackknife sofa. (But that brings its own problem with the kitchen slide/driver side imbalance!)

Hope this might help.

Knowing this helps me out. We’re not full time RVs and minimalists when it comes to packing RVs. Plus your UVW is 400ish lbs more to start. Thanks for your reply.

KCAllis,
We put Timbren SES on out '24 Chevy 3500 and they really stopped the squat and really improved the tow experience, less up and down and less roll. Cheaper and no maintenance. May want to consider.
Good luck,

I added super spring bump stops to my overload springs. I have a slide in truck camper that’s 2500 lbs and they seemed to help the squat. I may have to consider timbren or air bags if the bump stops aren’t sufficient. Thanks for the input.

To answer your 1st question, I believe they went to 8,000 lb axles and H rated tires thus the increase to 16k.
We have a 2026 310RL with a 2020 Ford F350 SRW and timberins. The GVWR in 2020 was 11,500 so you have more room than I do.

My loaded pin weight is 3,060. I do have a stackable washer/dryer, no generator and other than a fairly loaded 3 drawer tool box, not much that is heavy in the front. I'm about 300 lbs over weight and struggle to see what else I can remove to lighten the load.

I had about 4 1/2" squat before the timberins, 2 3/4 since installed. In previous rigs I've had both airbags and timberins. I decided on timberins this go around.

Bottom line is you're going be be close but unless you carry a lot, you'll be fine. The washer/dryer I have weights 215 lbs, so I'd be right on without it.

Any idea what your rear axle weight is when loaded? I think, like others, the rear axle is the limiting factor.

Weighed my 2025 310RL this past week. Here are my numbers with a 2024 Ram 3500 DRW with a payload of 5575lbs.
Truck alone
Steer axle 5360
Drive axle 4040
gross 9400

Truck with camper
Steer axle 5400
Drive axle 7800
Trailer axle 12380
gross 25580

That puts me at 3760 on the rear wheels pin weight. I am just tad over on GVWR of the camper though.

Are SRW? Or dually?

Just courious how your hitch is set up. Forward, at, or behind (2” or 4”) the rear axle. Just bought a Ram dually and setting up my hitch.
