Trailer Tech....sorta

With a gooseneck trailer, 15% of the weight is on the truck.

Say a trailer is rated at 15k.....

Assume said trailer is loaded to the max at 15K.

15% of 15k is 2,250 pounds

Theoretically, the trailer now has 12,750 pounds on it.

If this logic is flawed, please explain.

Yeah it's flawed.
The trailer still has 15K lbs on it, but only 12,750 pounds is carried on the trailer axles.

In my skewed way, this is what I was getting at.

So, if I have 2 7k axles which = 14k, I can still add 1,250 pounds and still be within the GVWR of the trailer.

Right?

I've been thinking about this so much my mind has gone numb(er).

I believe so, this stuff drives me nuts also.

Here's what I'm deliberating....

Triple axles carry more weight, but they are also a PITA for turning. I got the owner down to $6700 today. Needs a little work, but nothing serious, just cosmetic flaws. To be expected for a 1998 I suppose.

I have found it impossible to find a triple with enough height without buying new for $19k.

Wheres the side door?

If you are concerned about weight ratings then I would wait for a tripple axle. We have 2 for the bonneville cars and while 90 degree turns can bind them up, its a small price to pay for the extra load capacity.

How tall do you need the door to be?

you sure that thing will carry (weight-wise) two loaded jeeps plus whatever else you plan on tossing in there?

If my logic and math are correct, I'll have 1k for stuff besides the Jeeps. Cuts it close, but I keep looking at the price difference between this one and a new one....

You don't have to stress over this. Take a bathroom scale out to the garage and lay a longish chunk of square tubing across it with one end propped up on a block of wood. That end would be the back of your truck.

Get your proportions similar to what you see as to where the trailer tires are and watch what the scale does as you move weight around.

You'll find that the pin weight and tire weight added together always equal the total weight.

The more you put on the pin, the less the tires see. The more you put on the tires, the less the pin will see.

This would be wrong. The max trailer load is still 15,000 pounds. The max load on the axles is no more than 14,000 pounds.

If your tongue weight is 2,250, subtracted from 15,000, your axle weight is 12,750 pounds divided by 2 for each axle's load.

You can't load the axles to 14,000 AND have a 2,250 tongue weight without overloading the trailer 1,250 pounds.

That's the way I learned it.

Larry,

If you do buy that thing take it out for a test pull first with atleast one jeep in it. I looked at something similar before I got my camper. Mine was hitch vs 5th wheel. The weight of that trailer and my jeep was just within specs, but it was a bitch to haul compared to my current set up.

Larry,

Did you get the trailer yet? Go for it and carry at least two spare tires! And ,replace all of the tires that are on there.

Yep, picked it up a week ago. It had new tires on it, but 1 was flat so I put a new one on it. I have 2 spares, one new and one in less than good condition. Brakes are good and had the wheel bearings done as a condition of my agreement to buy it.

Spent the day yesterday wiring in 110v fluorescent lights and a 110 outlet.

No, but I have my eye on some 10k axles that I can get with brakes for around $2k
