Truck squat question

I have a 2001 ford F250 7.3 diesel with a 8ft bed. I have hewing helper springs on the rear. I have a generator, air hitch,37gallon fuel tank in the bed. When hitched I have a little over 3,100 pounds hitch weight. And when you look at my truck it is just a fraction above level.Been towing my 5th wheel this august for 16 years. And never had a problem.

So true in many cases and it’s easy to do but the wife and I always try to stay with minimal stuff. If it doesn’t get used at least once every few trips it’s gone. House is the same way.
Plus with this rig I can’t because I realize I can overload my truck if I’m not careful.

Our RV weighed 18,075# at the factory. Dealer added my 6500 Gen at around 400#. My RV after 6 years weighs 24,000#. Does not seem possible but the numbers don't lie!

If you are adding 3,160 to your rear axle, you would still be under your RAWR. This would mean your rear springs are capable of carrying that load. I'm sure you know that. :) If you want to keep the truck, closer to level, additional spring support will do that.

As loaded currently I’m at 3,160lbs rear axle difference between loaded/hitched and unloaded

Well are you sure you are within limits? Have you scaled your TV ready to go with all passengers? Have you weighed the combination?

16,200# GVWR 22% of that puts pin at 3,564#, + hitch, + stuff in bed.

IMHO that is too much RV for his truck!

Mine squats to level. Not sure the amount, probably 3". Truck beds are a little higher than level to begin with to compensate for a load.

That is EXACTLY how it should ride and at that stance you are on the overloads giving a better ride. Big mistake people make is adding bags and airing truck to ride at the same stance loaded as unloaded.

ZERO!!!

Show off!!

That is one thing I could not find in a used unit.

I was wondering if anyone was going to call me out on that statement. ;)

YES I have the factory rear air ride system and LOVE it! Top of back corner of the bed is 55" empty and 55" with my 6k pin weight pressing down. Truly an awesome system.

Beat me to it.

If you are up at 25% pin weight, that's north of 4000lb out of the trucks payload.

5ers are usually in the 20-25% range for pin weight.

Of course it depends on how much sag you have. Usually they sit a little high in the rear empty so an inch or two of squat usually just gets the truck close to level. If your headlights are scanning the treetops when loaded, airbags/sumo/timbrens are options to limit squat...this presumes you aren't over the weight limits for the truck.
