Trivial or not so trivial
We were set on finding a 5er that weighed about 8500lbs loaded for pulling. That would spec at about 75% of the tow capacity of the truck. If we go to 9000lbs loaded we spec around the 80% mark. Payload capacity is around 60%. Other than lower gas mileage, would the towing characteristics be significantly changed? The truck is a F150 Eco with Max Tow and HD Payload options.

I run at 95% capacity but I also don't live in or travel through the (hills).
Fuel mileage I chalk up to (rv-ing).
My unit pulls just as good if not better than my tt at which I was only at 65% capacity.
Slow down sooner take of slower.
When the dw pulls the rig I stick a post it on the dash (slow and wide)

I think a lot depends on what the shape of the front nose cap is. I went from pulling an 11,000# Copper Canyon to pulling a 14,000# Sandpiper and the Sandpiper pulls better at higher speeds.

Ah, yes I never thought about that aspect. Some caps certainly look more aerodynamic than others. I don't see many setups using the wind deflectors either. Would probably help many tow vehicles!

With what you discribe you will be near or over 100% for the TV. At 9,000 lbs times 20% for pin weight or 1,800 lbs, what is the limit on the TV? Ready to go what does the TV weight? Add the pin weight and you see what I am saying. My 5er with a limit of 9,950 lbs, 2012 V-Cross 275, should not be pulled with a 1/2 ton pickup, even though Forest River states that it is 1/2 ton towable.

I think you should be thinking about pin weight and payload capacity too.

Hi,
The TV max tow is 11,300lbs. The truck is on order. A comparable truck will come in around 6,000lbs. The GCVW rating is 17,100lbs. Payload capacity is 2,600lbs.
Are you adding the pin weight to the trailer weight to determine % of Max Tow for the TV???? Pin weight is part of the payload capacity.

Remember that the "Max Tow" F-150 is not a 1/2T truck in any respect. It is a 3/4T in 1/2T badging, or a "heavy half" at best.
What gets me is, to have a 2600lb payload, I would imagine you would need heavier rated axles. Now, since the standard half ton axles are in the 3900lb rating, and average payload is in the 1400 range, I would think you would need at least 4500-5k rated RA and a higher weight FA to achieve that. At what point would you just stop calling it a 1/2? It already has 3/4T if not 1T axles...
So, since I am having trouble finding a good source for the GAWR on a max tow F150, if you are still running <4k lb axles, how can you put >2k lbs on them and not be overloaded?

Quite right you are! While I'm not concerned at ever coming near the max payload, if I can't get the info from the dealer, I'll get the numbers off the truck. I should have the truck in the next couple of weeks if all is on schedule.

Three words, rear axle bearings. Ford and all of them sell parts and lots of them. Go to a parts store and see for yourself just how big a half-ton rear axle bearing is. And your going to put how much weight on it?
I see lots of half-tons with big RV's, I don't know.

On another forum, these are the numbers directly from the label on a similar truck:
GVWR 8200
Front GAWR 3750
Rear GAWR 4800
Max payload 2454 Truck options pull down the 2600 brochure weight
