Is there a general rule regarding how much weight is okay for SRW and how much is too much? We are thinking of a larger 5er and not sure how much larger will require a new truck too.

My general rule of thumb was always..... fiver over about 13,500 get a dually. Loaded pin weight should always be your guide. Of course its much more complicated than that. Duallies will be more stable when towing heavy. Duallies will cost you 50% more for tires. No answer is as pat as we would like them. Personally other than a under 30 foot fiver I would almost always opt for a dually for stability alone. But then again I dont take my fiver off road either.

Since you have a specific year and model of truck it would seem that you could easily determine if it could handle the trailer you are considering. I guess out of curiosity, what is the GVW of the trailer you are looking at?

Use this calculator: Calculator

Rear axle weight rating, and payload capacity are key factors. When you use the calculator the last value (Fifth wheel trailer king pin weight percentage override) will tell you what you really need to know

You will hear that a big 5er must have DRW but on occasion I pull a 20K load with my SRW BUT I can adjust the pin weight by where I position the load on the trailer. 5er manufactures save money by putting more pin weight (often 20%) than what’s needed for good handling...10 % is enough. This lets them use smaller tires and axles than what you will find under a TT of similar GVW.


This post is my opinion (free advice). It is not intended to influence anyone's judgment nor do I advocate anyone do what I propose.

Every truck of every brand, SRW or DRW, has a specified payload rating. And the specified payload rating for any truck, SRW or DRW, can vary considerably depending on that particular truck configuration. Example, an F350 SRW payload rating can vary as much as 1,000 lbs depending on cab, bed, engine, tires, etc. So there is no one number for all trucks.

Not the greatest advice, as at 10% pin an 5er would likely chuck badly! It is also difficult to get the pin that low in a normal 5er, GN flatbed no issue, 5er RV not so much.
We just stepped up to a DRW as a future proofing step.

We bought a SRW F350 CC, sb,4x4,6.7 in Dec '14 and at that time had a '06 Cedar Creek Silverback 33LBTHS. Pin wt, 1800, max GVW 13,800, dry 10,800. No probs whatsoever w/ that rig. May '17, upgraded coach to a '18 Big Country 3560 SS, pin 2900, max GVW 16,000, dry 14,000. With the BC, I was over on truck's GVW and tire capacity. Wasn't too worried about the truck (bad advice I'm sure), and really didn't think much a problem w/ the tires. That was until last year and planned trip to FL during height of summer heat. Now the tire concern started to really bug me. Short story, we traded in the SRW for DRW F350 for a total peace of mind with everything regarding the tires erased now. Would we have been okay w/ a SRW.....perhaps. But just had this nagging gut feeling that wouldn't go away. Was always told "Trust your gut instincts". With the DW driving, I didn't feel 1 bit uncomfy w/ her behind the wheel. Do I miss the SRW....you betcha. Like many, do see plenty of SRW trucks towing at least 15.000 lbs + RV.

If your looking for opinions, mine is: 15,000 lb trailer and under your okay w/ a SRW. Wanna go higher....get a DRW.
