Tell me how they work for your 1500 to get you under your weights.

For me it is a head game thing. I drove Semi for 35 years prior to retirement. 5th wheels are easier for me to pull have a better turning radius. As far as the smaller 5th wheels I have to agree. But a 1/2 ton pickup if set upright can haul up to a 28' foot 5th wheel.I don't understand the point of a 19-20' 5th wheel. You can tow a larger travel trailer just as well with a half ton and have a heck of a lot more trailer without all the headaches of worrying about payload. Within reason.
Goes way beyond my concept.No. Fluid dynamics IS physics. A different branch, but it is still physics.
And to delve further into this, the placement of the axles in relation to the overall length of the trailer is geometry, not physics.
I deal with this stuff daily.

I can "haul" most anything with a 1/2-ton. Towing and controlling it is an entirely different thing. I know of a bunch of 28' 5th-wheels that a 1/2-ton can "haul". I can't think of any of those 5-ers that won't crush the suspension and/or overload the rear axle.Show me a 1/2 ton, and a 28' 5th wheel, that it can tow.
There are a couple, if I recall, that a stripped down bare bones half ton could haul and not be overloaded. But again, you'd basically have to have a base truck with no options but a towing package and a V8, you'd need a regular cab and no shorter than a 6'4 box, preferably a long box to get out of a slider hitch...and even then I think you'd end up being close.I can "haul" most anything with a 1/2-ton.

And those are "dry" pin weights.Aside from the unicorn tiny fifth wheels, here are some of the lightest that the manufacturers make (calculating pin weight @ 20%). All of these are advertised as 1/2 ton towable. The last one is particularly comical. They do a great job at advertising dry weights and dry hitch weights to hit their numbers. Below are the real numbers (adding dry weight + cargo capacity).
Keystone Cougar 22RBSWE:
Length 25'11"
GVWR: 7,200 lbs
Pin weight: 1,440 lbs
Keystone Arcadia 246SLRK:
Length: 28'6"
GVWR: 9,900
Pin weight: 1,980
Jayco Eagle 24RE:
Length: 29'2"
GVWR: 9,995
Pin weight: 1,999 lbs
KZ Durango D240RKD:

GVWR: 10,500
Pin weight: 2,100 lbs
Grand Design Reflection 150 260RD:

If it's the advertised pin weight, it is the "dry" pin weight. I'll assume @nlambert182 posted the advertised pin weights.Right.... First one he posted is TT...
Second one is not 1500 Fifth wheel, it's for HD trucks.
If your going google crap, at least post real information.
@Tulecreeper and your are as bad as he is.... those aren't even close to dry pin weights.
Oh.... ok. I went by Keystone's listing. If you want specific info, go look it up instead of spending all your time trying to disprove everyone else. You have contributed nothing to this thread but trying to hammer others because you've been proven wrong too many times.Right.... First one he posted is TT...

I calculated the estimated wet pin weight. I never mention dry weights since they're irrelevant 100% of the time.If it's the advertised pin weight, it is the "dry" pin weight. I'll assume @nlambert182 posted the advertised pin weights.

For the second one.....

If you READ what I said in the beginning.... I clearly explained the pin weights. Nowhere did I ever mention dry pin weights. They're irrelevant anyhow.
If you want dry weights, go look them up. They're available for you to research yourself if you don't believe my numbers. The world is your oyster.
Dry weight + Cargo capacity = Gross Vehicle Weight
GVWR * 20% = the real pin weight.
You should be able to figure the rest out on your own.
I'll concede that the 22RBSWE is a TT after digging into their links. I'm not sure why Keystone lists them that way.
That said, then the lightest fifth wheel they offer is a 23MLE:
Length: 27'11"
Gross Weight: 10,000 lbs
Wet hitch weight: 2,000 lbs
Better?
Now..... explain how any of the numbers I posted are crap? They're literally the numbers from the manufacturers and you can look them up AND do the math. The only thing I didn't do, which no one with 2 seconds of RV knowledge would do, is use their dry weights.
