I need to figure out what my max load capacity will be with this new rig. Its a 95 VOLVO single axle with 22.5s adn a 48ft 02 Kaufman Pro VI Easy loader. The tag on the trailer says GVWR of 25900. It has 3 7000 axles and a 2 inch SAE king pin Fifth wheel on front. I know the newer Kaufman Pro66s are rated for 48,000 total by way of 30000 on axles adn 18,000 on htich. So useing their method i should be able to get 21,000 from my axles cap., and 18,000 hitch for total of 39,000?
Help trying to figure load capacity on Kaufman 6 car trailer

We run a very similar setup, although we run full dual tandems and air ride so my trailer capacity would be higher, what are you going to run as a registered weight? If that trailer weighs 14,000 (guess) and the truck is 16,000 (guess) you will be 30,000 empty you COULD reg for 54,000 and BYPASS 2290 heavy use road tax. This would still allow you 24,000 for vehicles.
As long as you are JUST cars in most cases you could get six cars on that, obviously if you are hauling p/u's your cap. will be limited. Remember you really gain nothing reg. for OVER 54,000 with that setup because you are limited to 21,000 trailer axles, 20,000 truck rear axle, and a 12,000 ft axle, so you are only going to be able to haul a total of 53,000 in most states anyway.
Hope I didn't confuse the issue.

I got to go weigh the truck and trailer empty to get it registered in texas, so i will know more when I do that. Im also looking at the tires on the trailer, they are 235-85-16 load range E tires, rated at 3050 with 80 lbs air. Looks as though that will limit me to 6000 lbs per axle on the rear, unless i get some more heavy duty tires. I thought the newer E range (or whatever they call it now) tires could handle more weight than that, or am i wrong?

There are some G and H load ranges available I believe Goodyear makes them, they should come in at 3500# per that will give you the 7,000 on your axle.
HOWEVER, I can tell you from exp. that running those tires at full max weight and you better be carring a couple of spares. Also I am assuming that this trailer has electric over hyd. brakes? If it does you WILL be putting brakes on the trailer on a regular basis, you will want to check but in most cases on those type of trailers they are using an RV type axle, they are NOT really up to commercial use and 150,000 miles a year.
Don't take this the wrong way, but Kauffman is not really noted for having a quality trailer, google kauffman trailer problems, you will get pages. If you are serious about this business at some point you will want to step up. Go on the truck paper under trailers, you will find TONS of Kauffman or trailers built like them for sale some only 6 months old.
IF you are only hauling lite, AND you are the only guy using it, AND you are meticulious about maintenance it will do you ok. But I doubt that it will last you for years or hundred of thousands of miles. Again, not trying to be a hard ###, but I have been in this end of the business for over 20 years, this is just what I have seen.

I do all my own mechanical work, maintenence, and welding for that matter, and keep a close eye on everything. My 3 car wedge trailer i just sold was a 1987 Kraftsman (when kaufman was together with them) and it was built hell for stout, and so is this trailer. I havent found a cracked weld or patch anywhere on it, and its 10 years old.
The trailer that everyone badmouths are the 5 or 6 car Kaufman haulers with only 2 10K axles and only 4 17.5 tires. I actually saw a factory sticker on one of them that says you should not drive over 55 mph loaded or severe tire damage can result!!! Those trailer are KNOWN to blow a lot of tires. Thats why I steered away from those. I was parked one night at a motel 6, and even had a guy try to trade me one of those trailer for my 3 car wedge, but I said NO WAY!!!
If I decide to keep this trailer, Im probably going to put 3 new 10 k axles under it, and either G rated 16.5 tires of maybe even 17.5s like the new Pro 6 ones have. I actually would like to move up to a Cottrell, SunValley, or WallyMo with dually air ride axles that can easily handle 7 or 8 cars when finances permit. You got to start somewhere though, and I got a really good price on this truck and trailer. -
Understand about starting somewhere, believe I had next to nothing when I got going, as long as you are aware of the trailers limitations (weight) you will be fine. We haul mostly bigger vehicles, shuttle buses school buses, limos, ambulances and fire trucks that's why we needed a stouter trailer than what most auto haulers are built for.
IF you can do all of your own work and you got a good price on the rig you should not have much going out in expenses, that will help you keep your cash flow up and you will be fine. When I had first answered your post I did not realize that you were already hauling, I assumed this was your first T/T.
Hope everything works out well for you in your new venture.

Interesting thread fellas. Im also trying to step up from a wedge pick up. Does anyone lease or rent a 6 car trailer? Can either of you tell me more about ifta? What kind of fuel mileage you getting BH? thanx...

I'm getting 6 to 6.5 mpg, get 7 if I'm loaded light. My truck has a lot of miles on it, and is only 350 hp, and would probably do better on fuel with an overhaul, but i'm probably just gonna buy a newer truck later. Im not having to file any IFTA taxes because im only running in the state of Texas. This was primarily due to limited start up funds about a year ago, but i have stayed so busy i have not had to worry about crossing state lines just yet. I will do it in the near future though, after i get to where I have my equipment maintenance up to speed enough that I trust it for a long haul.
