what is to long or to heavy for a SRW

[papermakermd]

We are thinking of moving up to a fifth wheel and are considering the 337RLS. I realize a move to a diesel will be necessary. I do not want a dually under any circumstance. I know this is a loaded question so please only answer with your experience with what you are using or have used. We are currently towing a 297 RSTS which is about 34 ft.

We have a 337RLS being towed by a 2020 Ford F-350:SRW Lariat Diesel Crew Cab Short Bed. The limiting weight is Payload. The truck is a highly optioned Lariat except it doesn’t have sun roof.

Payload is about 3500 lbs. I’ve had 3 F350s and current special ordered 2020 F-350 has a payload of 3484 lbs. my others 2017 & 2019 were 3500 lbs and 3523 lbs. neither had a sunroof.

Here are real world weights
2,800 lbs pin weight loaded for travel
450 lbs = 2 adults plus dog and parrot in cabin
37 lbs Andersen Ultimate 5th wheel hitch
71 lbs Backflip F1 bed cover
50 lbs misc stuff in truck bed (bedrug, safety cones etc)
————-
3,408 lbs so we are just under payload capacity.

The Andersen hitch at 37 lbs is 200 lbs lighter than most other 5th wheel hitches. We love the Andersen.

I installed disc brakes on the reflection which was a huge improvement in stopping power.

Have you always used the short bed. If not did you see any difference between SB or LB

I have a 2020 350 Lariat 6.7 Diesel long bed SRW and the cargo capacity is 4,541 lbs.

Thanks! I know you get more payload with the LB. I won't need that much payload. I'm more concerned about how the SB handles length versus LB.

I had a F150 sb and now my 350 lb. I didn’t notice a huge difference between the two. The 350 has a larger turning radius but I’ve been happy with the handling of the long bed.

Thanks! for the info. I appreciate your input.

14,000 lbs max? You'll be legal unless you load really strange with a new 350 class truck. Diesel eats up payload, but I'd be surprised if you get over 3K on the pin with that trailer.

I know you said you don't want a DRW, but, even though a SRW, in your case, I think will be "legal", a DRW will unquestionably do it better. If you're not going to tow a ton, or you really can't own a DRW, I get it. But having now owned a 450 for about a year, I've had exactly 0 situations over that year where the DRW was a problem outside of not being able to use automated car washes and drive thrus. I've even parked it in an airport garage a few times, you need to pick your spot, of course, but it does fit. Honestly, the length is harder than the width, but the length helps a lot with towing stability. It's all about compromises.

Let me start out by saying it's not about length - it's about weight and especially pin weight for the trailer and true payload capacity for the truck.

We spent our first 4-1/2 years full-time in a Reflection 337. We started out with a GMC Sierra 2500HD CC SB with the Duramax/Allison power train. The Reflection never scaled with less than 3,000 lbs. on the pin (no washer/dryer but did have the front AC). It usually came in around 3,100 lbs. pin weight. This is with full propane but nothing in any of the waste tanks (the fresh water tank is over the rear axle on the 337, so it doesn't really affect pin weight). We were never more than 60 lbs. over the sticker payload on the truck and still had rear axle and tire capacity to spare (several hundred pounds). With Timbrens on the truck and a dampened pin box, the rig handled very well... most of the time. On curvy mountain roads there was an "on-the-edge" feeling to the handling and stability. When we were presented with the opportunity to trade even for a dual rear wheel 1-ton truck of equal value, we jumped on it. There is a noticeable difference and I'm no longer worried about what would happen if I had a rear tire failure on the truck at highway speed. It also gave us the additional payload capacity to move up to our Solitude when the time came.

I wouldn't rule out the new 7.3 gas motor. It will tow it with no problem and give you more payload capacity. My F250 with the 6.2 gas motor has over 3900 pounds carrying capacity.
