Axle Limits
So I have a 1986 F-150 2WD. It's the regular cab long bed "heavy half" model.
I know the GVWR is 7000 but I don't know what the rear axle rating is.
I have Big O Open Country tires with a "C" load rating. These are great tires.
I'm interested in getting a smaller 5th wheel next year so I'm doing some checking with my knowledgable brethren.
When looking at a used 5th wheel trailer how can I determine the pin weight?
Thanks in advance,
Dan

First off I wouldn't tow with C rated tires, with your truck I would use "at least" a D rated depending on how big of a 5th wheel you get. The trailer you get will have a spec plate on it up front, the pin weight is usually about 20% of the total trailer weight.

Cyncwby, thanks for the heads up. Ya I did a little looking and "C" rating is a little light.
I have heard that a bumper pull trailer figures about 10% tongue weight, so a 5th wheel set up is 20%? Then how are 5th wheel hitches rated and do you buy them for gross weight of trailer or pin weight?

Agree^^ I've got a 12 k trailer and bought the 20 k hitch. More is better, less ain't.

Yea don't go cheap on the hitch, I did a lot of looking and finally found the hitch I wanted. It is overkill for my setup but overkill is good, never have to worry about .....geee, do I have enough truck and is my hitch up to the task.

I'm with you Cowboy, redundancy and overkill all the way, never look back.
I've never, NEVER been sorry for buying a bit more than I need.

But after it began to sell like hotcakes, to make a few extra bucks, the IDIOTS at FoMoCo installed "C" rated Firestone tires, then underinflated them to give a cushier ride.
Guess what happened next?
A contributing factor: The Firestone tires were defective.
