Confused about what kind of truck size?

Hi Everyone.
Just joined the forum today and I am hoping to receive some input.

My wife and I are in the process of purchasing a Heartland BC 3070 RE.
We have a vacation home in Florida and want each year 6 months traveling through USA.

Now, I am however confused about what kind of truck size?
The research on the Internet does not provide clear statements.

All major brands, whether 250 / 350 or 450, the same numbers for the towing capacity. (with the same Axle Ratio) What I have to say, we decided for a diesel.

Here are the facts:
Ford:
GCWR 23,500
Towing 15,700 to 16'600
only double wheel has more DRW 23,500 to 24,900

Chevy:
GCWR 24,500
Towing 16,900 to 17,900
Dually 22,600 to 22'900

Heartland:
GVWR 15,500 lbs
Dry Weight 11.740 lbs
Hitch Weight 2,315 lbs
Axles (2) 7,000 lbs

So, whether I buy a 250 or 350 diesel, the GCWR is the same and also the max towing is equals. According to the manufacturer,
this should be no problem with a diesel. (??)

Now I have entered these numbers on this website.
Result: 5th Wheel Towing Max is 7500 or less.

I see many travelers with a petrol engine (2500) pulling a 5 wheel foot with 40th
according to this site, these all go in the illegal sector.

Most 5 wheel trailer have a GVWR between 11,500 and 18,000.
Most diesel truck have a GCWR between 22 'and 25'000.

Therefore must each truck with a 5 wheel with GVWR of more
than 15,000 a be dually.

Or what I have misunderstood?

I look forward to becoming well informed by all the experienced people that are members of this forum.

Thanks for your help.

IMO, you will probably want a diesel if the trailer weight is over 13,000 lbs or so. The extra torque of a diesel is much better at handling the weight.

The towing capacity of a 3/4-ton and a 1-ton may be similar, but the difference will be in the payload. Payload relates to the pin weight of the 5th wheel, and pin weights typically run from 15 to 25% of the trailer weight. Because of the cavernous storage compartment in the front of most 5th wheels, your pin weight will probably be significantly higher than what is shown in the trailer manufacturer's brochure. That means a fully loaded 5th wheel with a GVWR of 15,500 lbs could have a pin weight of almost 4,000 lbs.

Check the payloads of all the trucks you're interested in. The payload of the truck minus passengers, hitch, options and anything else you're carrying should be more than the expected pin weight of the 5th wheel.

You definitely need an F350 for that 5th wheel. It's not just the towing part that is important, it's the trucks payload capacity. F250's or any other 3/4 ton diesel won't have the payload capacity for the loaded pin weight of the 5er.
A 1 ton diesel should give you 3500-4000lbs for pin weight and all other gear/passengers that's put in the truck.
An F450 is overkill. I would go DRW with the F350. It might be a little overkill but if you're traveling for 6 months at a time then you'll want a solid tow vehicle. You'll get better control and be able to pack pretty much all you want.

I'm sure power and braking wise, my GMC 2500 Duramax could tow that trailer easily except for the before mentioned payload with the high pin weight of a fifth wheel. Gotta go with one of the one tons to get the springs and tires you need to handle a larger fifth wheel.

I agree... My new 15 Silverado 2500 4x4 crew cab Duramax weighs 3080 on the rear full fuel and me... No hitch... Factory rating (for what its worth) is 6200 on the rear axle... (single wheel of course) If you figure 20% toung weight, thats over 3000 lbs,,, which yes my truck could handle... Just figure in how much "stuff" you are going to carry.......

Where do you get a 7,600 max tow. You can legally tow that trl with any one ton made by the big 3

If you are towing a 5th wheel, why not buy a 350/3500? It has the same footprint, same tires, and only cost a couple hundred dollars more. It will give you 1000+ lbs more GVWR. I drive a F250 for a daily work truck, but if I were towing a 5th wheel, it would be a F350 for sure.

Your trailer looks to be awfully close to the safe line. While a 3/4 or 1 ton single wheel may work it may not be your safest choice if you load the trailer with the stuff that many people add I am willing to bet that when all is said and done you will be over 4k on the pin weight which is over the weight limits. Add to that if you blow a tire on the rear at that weight you have a higher chance of losing control. I have a DRV 36TKSB that weights in a just over 17.5k with a pin weight of 4500lbs and my 2015 Chevy Crew Cab Dually is just about maxed out for weight if you figure in fuel, people and gear.

X2 - There's very little difference in price and a big difference in payload capacity. You probably won't be able to tell the difference in ride between a 3/4-ton and a 1-ton either.

The Big Country is just about at 100% of the pin weight carrying capability of any 3/4 ton diesel truck. It leaves you little to no leeway.

Go for a diesel 1 ton dually and you'll be fine. You'll also be ready in case you want to upgrade to another full size fifth wheel trailer in a couple of years. The dually is just marginally more expensive on front end.
