Critique our choices

5th wheel is a new Keystone Montana. 35 foot. Full time for at least 2 years. Need 4 seasons. Weight GVW 16,350 lbs. Hitch weight 2,400 lbs. Tow truck Ford F250 extended cab long bed diesel 4x4, SRW, Lariat trim. 2016 or newer.

We don't need the rear seat.

This is a truck about like the one I had 8-10 years ago when we sold our camper and bought a beach condo. A big mistake but not pertinent. My only problem with the Ford I had was even with auto engaging of the front wheels I still had to get out to twist and lock the hubs. The previous Dodge I could do it all from inside the cab.

Something else. The Ford internet site listed maximum 5th wheel towing at 27,500 lbs that seems like a lot.

I think if you could find an F350 instead of the F250 you would be much better off.

Sounds like that pin weight is for dry weight. Loaded will probably bee 800-1000 lbs. higher.

That weight is for a F350 DRW. 2016 SRW maxes out right at 16kish, depending on options. I think the 2017 F350 SRW runs up to 20k, but the payload is going to limit you.


Will the F250 tow it? Yep, most likely with no issues. The 2016 F350, which I used for a year with my fiver, will be a little more comfortable. That weight will make you squat pretty good, you may want airbags/Timbrens/whatever to keep your lights on the ground.

cfowler has a good point--the pin weight should be over 3000 for that trailer loaded to travel.

Truck is too light or 5vr is too heavy. Not sure if youve pulled the trigger on either, but you should recheck the math. That combo wont work.

Just noticed this.

"Weight GVW 16,350 lbs. Hitch weight 2,400 lbs."

Some reason that cant be right. 16,350 - 2400 = 13,950. Youll have 2 x 7k axles carrying 13,950. If true, youll be breaking springs, bending axels, and going through tires prematurely.

Hitch weight is generally 20% of the GVW, so more likely hitch weight is ~3375

Just recheck you numbers and math.

Always....ALWAYS calculate what truck size you are going to need based on the GVW or the trailer! In your case, 16,350 lbs GVW. Now do the math on the pin weight..... 16,350 x 20% = will put you right at 3300 lbs of pin. Now add the 5ver hitch...roughly 175 - 200 lbs and now you are at approx. 3500 lbs. You still have to do some more adding to those numbers....Driver's weight, passenger(s) weight, tools, firewood, extra fuel, grill,.....anything and EVERYTHING that goes either in the truck cab and/or in the truck bed. I have no idea what all you will be taking, but let's just throw a number out there for the above mentioned items....and you can add or subtract as needed....another 750 lb. So now, we are looking at 4200 lbs of weight that you will have to be able to handle with the truck's available payload capacity. I doubt you are going to find anything in a single rear wheel truck to do it, so most likely you are going to need a Dual Rear Wheel truck, as in F350 Dually. There is no way that I would even consider an F250 for a trailer that size. The added stability of the Dually will make your life much more enjoyable too, when towing.

And just as a reference point.....the truck you described in you original post, will be good for maybe 2400-2500 lbs of payload capacity.....maybe!

Great information.

I'm thinking we may have to modify our plans a little. We have not bought truck nor trailer yet.

Our second choice, actually my wife's first choice and by default my first choice is a Compass by Palomino, 36'3" overall length. Specs on the brochure are hitch weight-2132, unloaded weight-10869, GVWR-13869. Concerning the GVWR, gross vehicle weight rating, why have the "rating" tacked on the end? I'm assuming this covers variance in construction materials, since the GVWR is to the pound and not rounded off.

There is a difference between GVW and GVWR. The difference is the trailers payload. GVWR - GVW = CCC (cargo carrying capacity, aka payload)

GVW is what the empty trailer weighs.
GVWR is what the maximum the trailer is allowed to weigh after you have put all your stuff in it, including full water tank, LP tanks, clothes, camping gear, etc.

After you have the rv all loaded up, you should take it to a truck stop scale and weigh both truck and trailer together.

Your truck also has these same limits.

As already mentioned--hitch/pin weights on fivers are generally in the 20% of the gross weight. In the Compass, this is very close on the unloaded weight x 20% = 2174.
Using the GVWR of 13869 that is what the trailer could weight if loaded to max, that hitch weight will be around 2774. What ever truck you are thinking about will need to be able to handle 2774 PLUS what is already on the rear axle as loaded to go camping.
Then there is the GVWR of a normal 250/2500 3/4ton pickup, usually 10000. Check the door jamb sticker on any pickup you look at--it will have the available payload--take 2774 from that and see what the number is.
3/4 ton pickups are great trucks for towing travel trailers; when you upsize to a fiver, it will have to short/light or both or you will be exceeding a lot of the mfg numbers.
Having said all that--currently on an 8000 mile trip around the states and the number of 40-43' toyhaulers being towed by 3/4 tons that I have seen is amazing.

Delham, I've been doing a lot of research in preparation of buying a truck and RV. One of the places I started was with towing capacities. Your posted numbers seem to be a stretch and I can only base that on research and math. I would recommend to study the towing guides and thoroughly understand all the terms GVW, GVWR, GAWR, GCWR, etc for the tow vehicle and the trailer. For me it became a bit overwhelming so I broke it down into a spreadsheet until I have a good understanding now. Good luck.

You pushing the limits of a F-350 SRW with those weights. Do not bother with a F-250. You'll be sitting on the bump stops.

Again, pushing the limits on a F-350 SRW with either trailer. I'm a big SRW advocate with the understanding that you may need to do some weight management with them.

Calculate your pin weight as 20% of the GVWR of the trailer. Ignore dry weights and manufacturer published pin weight on the trailers. Just to give you an idea - my F-350 XLT (note: not a lariat) only has a payload of 3640lbs. a similar F-250 would be around 2100lbs.

The first rating you are likely to exceed with any 5th wheel will be the truck's payload capacity.
