Just had a 2014 Ram 3500 Longhorn willed to me. It only has 52k on it, and only pulled a 7500lb RV. Even with air bags on it, I know it's really too small over the long haul for a 4 car drop deck or stacker. I'd really like to get a 4500, but I figure I can put another 50k on it, and still have good resale value. So I'm looking at the Appalachian as a 2-3 car for now, but ultimately I want to have at least a 4 or 5 car. In particular the Appalachian Micro 4, the Infinity, and the Kaufman ez loader. After reading here, and looking at the Infinity which is 5 miles south of me, the Infinity is a no brainer, but that's going to take saving some money first and having a good solid clientele. The Appalachian doesn't sound very solid, and the Kaufman has a load height restriction on the #3 spot.
My question is.....per my math......how did you guys not be overloaded on the GVWR for the truck? In particular putting a 4-5k vehicle in the #1 and 2 spot? I know having the heaviest vehicle in the #4 spot helps offset, but the payload on this truck is only 5-6k for the 14k GVWR. On the 4500 the payload is 6-7k for a total of 16500k GVWR, which makes the math there questionable as well(same question/issue). Now the GAWR is fine which is like 9k and 11k on the 4500. No problem there or the GAWR and GVWR for the trailer. Not completely worried about the GCWR either. What does DOT actually measure? I see lots of trucks on the road, and lots of pics here and there from you guys using the Kaufman in particular. So is my math off? On the farm we just made sure the load was balanced with about 15-20% tongue weight, making sure the truck didn't squat too bad(no air bags in those days). We weren't totalling anything over 20-25k though. How do you load without being overloaded? Thanks, Chris

That is the biggest problem with the pickup truck and trailer rigs. Yes, they are inexpensive to get started with but it is very easy to overload them and become unsafe. Your math is correct, it is a balancing act to get both the axle weights and gross weight correct.
The DOT looks at several things when checking weights. First is the overall gross combination weight rating, then the registered weight or the combination followed by the gross vehicle weight ratings of each unit in the combination. If you are under those weights then they will look at either individual axle or axle group weights. After looking at the axle weights they will then check the tire load ratings on each tire to be sure you have the correct rated tires on each axle to support both the gross weight rating of that axle and the actual weight on it at the time they inspect you. Pay attention to this as many people cheap out on their replacement tires and put a lower weight rating on, or the tire shop (especially big chain places like Firestone) does not understand what you are doing with the truck and sell you a less expensive tire that is not legal or safe for what you are doing.
In your example above, you will need to take into consideration the tare (empty) weight of both the truck and trailer, the axle ratings of each vehicle, and how the weight is distributed between the truck and trailer. Example, a tri-axle trailer will distribute weight differently than a tandem or single axle trailer because the wheelbase and bridge is different. Also, the type of hitch and where it is mounted in relation to the center of the rear axle will change how much weight is carried on your steer, drive, and trailer axles. Without the actual weights of your truck hooked up to the trailer in question all I could offer you is a close guess, the trailer distributor should be able to help with the actual math calculations with the info from your truck and their trailer. You can learn more about this by researching the bridge formula, this is the math formula most jurisdictions use to calculate how much weight any given combination of truck and trailer can carry, you can also use these measurements and calculations to roughly estimate how much weight is going to be on any axle as you change configurations.Studebaker Hawk Thanks this. -
Consider this, right now that truck is worth 40k. After running it in this business, it will be worth 15k in no time. Take that into account when figuring your business plan
Hulld, KANSAS TRANSIT and brian991219 Thank this. -
Brian, thanks for that info, it's exactly what I was looking for. Terry, thanks as well, however, thanks to these forums, I knew this truck is a bit too small for a 4 car, which is why I'm looking at some 2-3 car haulers, and some of the shorter drop decks, to haul freight as well maybe. The business plan right now is easy since its free! The business plan in the future however will depend on the performance of this truck, and how I feel about how the 4500 will do better. It gets an upgrade in 2019, and the 5500's are geared too low, for fuel, as well as too rough of a ride by itself. I'd look into the single axle semi's mentioned on here. I've got some cash to ride around for a few months, plus it's all tax deductible, and the truck will hold it's value for a few more years and 50k+ as most of these used trucks have some miles. So thanks again guys! Chris
Bluegrasscf and brian991219 Thank this. -
Brian, so a little further for clarity......The GVWR for the truck,is the real problem here right? The tire rating, and GAWR is fine. Like I said, in the old days, we went by how far the truck squatted, and the approximate weight of the load. This truck has air bags, and the 4500 as far as people say, won't squat hardly at all, but you'll be over the GVWR. Chris

Terry, I don't understand how the rear axle rating is too low, it's about 9K. However the payload is about 6k, depending on how much the truck weighs with fuel, people, etc. Either way it can only total up to 14k, and the published weight of that truck is 7800-8600 depending on what you trust, but the scales don't lie, and it can only add up to 14k. The rear axle rating along with tires, tell how much they are supposed to be able to handle, and not be destroyed. At 9k that's a lot and doesn't make sense, because with the GVWR at 14k, you'll never come close to that 9k, but they make these parts this strong, because weight can be re-distributed when you stop hard, or take off hard, so it does make sense. I just thought they'd put that GVWR up another 1k or so. It's a legal thing, to protect the manufacturer and dealers. I used to be a sales manager selling cars and I had to know a lot of this, but never knew what DOT would measure, and how GVWR, GAWR, tire ratings and such would figure in. I knew that the truck had to be able to handle things, the tires had to be able to handle things, because we put about 20k behind a 96 Ram 3500 pulling that around the farm with rough roads, and down the road 10 miles or less between farms. This is why I actually believe there should be a different license for anything under 30k total including RV's and farmers, because there are a lot of bad drivers out there, and they are getting by scott free. But then again there are semi's, as well as all cars getting by scott free. Why do we even have a license or law enforcement, when so many laws aren't enforced? Sorry got on a rant. Commercial licenses should start at just being for hire, but there should be a license for anything over 50ft total, then 70ft or more, and 30k or less, and 30k or more. I just think the regulations for the lower weights/lengths should be a lot less regulation, but then again we're talking about government here huh. Sorry for the rant. Chris

Pulled a Kaufman ez loader IV with my 03 dodge dually and then my 08 dodge dually.
My gvw combo was set at 34,000#
I ran ny to fl and crossed the scales an average of 20 times going down and back and never ran in to an overweight problem either gross or axel.
With that being said everything terry said about drivability and braking and maintenance is absolutely true.
I still run ny to fl but do it now with a tractor and an air brake trailer if that tells you anything.brian991219 and Terry270 Thank this. -
Did you ever weigh your dually and Kaufman @Hulld
