6000 lbs on the rear wheel is going to be 4000lbs payload max.

6000 lbs payload will be at least 8000 lbs on the rear axle. For that, you are going to need more tires and a heavier rear axle.

I know you are still in the dreaming mode, and I hate to squash guys dreams, but this truck is a really poor fit for what you are trying to do. Even if you get the try upgraded to safely handle what you are talking about, you still have a people problem. If you add that rear jumper it will work for a family of four, but for how long?

Best bet ... Start looking for a similar super cab camper special f350. You will be worlds ahead. My kids are 4 and 1 and there is no way this is even close to working for us.

Just one guys opinion.

 

Cool thanks ill keep ya updated on my build

 

The load range letter is only a rating of side wall stiffness and is a newer representation of 'ply' as in '6 ply' (Load range C) or '10 ply (Load range E).

The max load index rating is always stated in numbers with a corresponding PSI value.

Load Range and Load Index are often brundled together as meaning the same thing and they are not.

There are D range tires with a higher load rating than Es and there are E range tires with lower load ratings than Ds.

There are reasons to keep the factory 16.5" camper special rims. They are 9.75" wide and accept factory hub caps so you can have the wide look but with the factory look. If you can find a source of military take offs (there are a few if you know where to look) you can get a 37" tall by 12.5" wide tire for relatively cheap. (About $200 for a good tire.) The "OZ" on them is a marker that they have a higher ozone resistance.

There are reasons to 16" rims too. But make sure your brakes will clear and you get the correct offset before you. Lots of the 16.5" military tires are 10 years or older and chain tire shops won't mount them. They can be hard to balance, but I have found that balancing beads work fine. The design of the 16.5" rim's bead seat is wider so it will take a higher load; the primary reason for its design. But it has to be tapered more so that the tire bead can be installed/removed without too much force. This makes the bead of the tire more prone to pop (inward) off the rim if the tire pressure is significantly lowered. Some opine that this is an unsafe design because of this. I think the wide factory camper special rims look so good with these big tires that I would run a tire pressure monitoring system (TPMS) if I was truly concerned about the rim design. I am not.

Thanks for taking the time to share your build project!!!

 

Thanks for the advice i realy appreciate it ill have my tire guy take a look for some military tires. Ya they told me it might be a fight to change them but there always up for a challenge.

 

When I was a boy my Dad (and Mom) bought a 74 F-350 Super Camper Special. That's the one with the extended 139" wheelbase. It had a 460 and a Dana 70 with 4.10 gears. That thing was a beast and would pass everything but a gas station.
Also, I remember the first time I pulled the intake manifold off an FE. I thought I must have missed a bolt somewhere, there's no way it could be this heavy.....

 

140" Wheelbase: 1973/76 F350 Regular Cab Super Camper Special; 1973/79 F350 Regular Cab Trailer Special; 1977/79 F350 Regular Cab Camper Special.

Ford dropped "Super" after 1976.

 

If there's anybody who knows their specs, it's you! Somehow I had it in my head that it was extended by 6", I guess it was 7". I remember it was obvious by looking at it that the rear axle was moved back, and it was no fun dropping the spare tire out of that side compartment.

 

Yeah Boy howdy that intake is heavy as hell im replacing it with a aluminum one (less weight from 80 to 30lbs and heat reduction)

 

Does anyone have the formula for suspension weight
Like if I change to a Dana 80 rear end upgrade to some F350 leaf springs how would I formulate how much I could carry
That's an example I'm not doing that to the F250 but all the little goodies that I take off of it i may put on my 100

 

Before you spend any more money on This regular cab truck. Move your couch out from the wall one foot and but that youngster on a box behind it with a game boy or whatever you intend to for them to pass the time and see if they can take it. 1 foot is not much room. Besides in most states it won't even be allowed seating as it was not installed by the manufacturer. Also that is not a lot of room if you were, God forbid to hit something or someone hit you what is their head going to run into most standard cab seats have little to no padding on the back of them. You keep saying yeah I'll think about that but is sure doesn't sound like it. You are about to put over $6,000 into a truck that is going to give you a very limited lifespan. Kids grow very quickly.

 

Understand what you're getting at but what you fail to realize is this is still in idea stage I haven't even been able to measure a Ford Ranger extended cab to see what the interior measurements are.
When I get one to come by the shop at the junkyard and I measure it and compare it to my truck I will see whether or not I like the idea of changing the interior is out or not
That one foot of space is from the mega seat that is already in the old truck I'm hoping to add maybe four to six more inches to that foot with a smaller bench seat
But again this is all an idea until I am able to get a ranger to measure the interiors and measure the seats and see how they would fit inside my old truck
If it doesnt look to fit how i would like it I'll be going back to the drawing board and trying to figure out another way of squeezing 4 into a three-person truck
like my old man always said if you can't raise the bridge lower the water

 

Well there is no LEGAL way you can do that. Putting 4 people in a standards cab pickup. Unless you are shorter than 5 feet you won't be able to drive the truck with the seat all the way forward! I had an 85 F150 supercab and just moving the seat forward a couple inches made it harder to drive comfortably. I had 2 adults and a baby in the back seat. That is one of the reasons I now have a Super Crew, plenty of room front and rear. for 5 adults when needed.

 

I totally understand its not legal
As for the small drivers area. That doesnt bother me with the mega seat all the way forward i still had plenty of room to work with. An im used to driving military cars with waaaaay smaller areas.
I will most likely change back to the stock seat after the america tour which is the reason for this build so im not worryed about the kids fitting later just for now.
I feel modifying the seats for the one road trip is better than buying a whole new truck
Because after the America tour it will be my daily driver. If we need more seats then we will just take the rover

 

Since you're still in the brainstorming phase... People can legally ride in the back of a pickup if there is a seat bolted to the frame with seat belts. Kinda loud back there but maybe some sound proofing on the floor would help. Then pull a camper behind instead of sliding one into the bed. A little creativity with the cap for the bed...tv, refrigerator, etc would help with the comfort.

 

Actually like that idea but have to write that down in my book ideas for my truck
I'll come back to that idea when I'm actually putting down pen and paper on what one I want to get for my camper I'm leaning towards Slide in because I don't really like to tow
but again I will reevaluate my options after the truck is built and I'm looking at campers
