    So, I'm trying to figure out how much weight I can carry to determine which trailer to buy.
    The truck is a 2016 Ram 3500. According to the ram trucks website the numbers for the truck are:
    Base weight: 7843 lbs
    GCWR: 30000 lbs
    Max trailer: 22000 lbs.

    Base weight is the truck dry correct? Would it be safe to add 1,000 lbs for body weight, 60 gal aux fuel tank, supplies, etc..? So that would be 8843 lbs. I will round up to 9,000. With max GCWR being at 30,000 lbs, I can haul a trailer w/ cargo that is 21,000 lbs?

    The big tex website lists 16GN single wheel tandem axle at 6330 lbs dry and GVWR at 17,500 lbs. That would mean I can put cargo/equipment on it that is 11,170 lbs.
    It also lists the 22GN tandem dual wheel trailer at 7,800 lbs dry, 23,000 lbs GVWR. That would mean I can put cargo/equipment on it that is 16,100 lbs.However, at 16,100 lbs cargo on trailer 7,800 dry and truck at 9,000 lbs, I would be over the GCWR of 30,000 lbs correct? That is 32,900 lbs. Therefore, I can only put 13,200 lbs on the trailer to be under the 30,000 GCWR of the truck.

    Finally, my question. Is the 2,030 lbs capacity difference between the 16GN and 22GN worth the extra price of the 22GN? According the numbers, I could never fully use the capacity of the 22GN due to the truck limitations? I don't exactly know the price difference but I'm sure it's substantial.

    I appreciate your help.

    The Ram GCWR is not a DOT rating.

    The numbers to be concerned with are what are the tires rated at and what is your License plate registered at.

    Don't exceed tire ratings and don't exceed plate registration.

    IMO, trailer duals are worth it. You may lose 2k payload in your example, but you gain 6k in axle rating. My experience is that you need to be able to load the trailer axles pretty heavy to maximize real-world payload.

    The GCVW of the truck and the trailers that you are talking about are above the 26,001 pounds which means you will be required to have a CDL.

    With that understanding the limits that the DOT will look at are what the truck and trailer are registered for in total. Now you must look at the vehicles capacities. Add the front truck axle plus the rear axle of the truck plus the rated capacity of the axles of the trailer. This information is located on the stickers that are on the inside of the drivers door and the sticker that is located on the neck of the trailer. Add those 4 number together to obtain the maximum weight that the combination can haul and be legal. In addition to this limit the weight rating of the tires and wheels becomes important.

    On each wheel there should be a stamped max weight. On each tire there should be a max weight. Your load must be located on the trailer so that the maximum is not exceeded on any one axle. The two tires may be rated at 4500 pounds each thus the axle could hold 9000 pounds according to the tires. The wheels may be rated at 4300 pounds times two equals 8600 pounds thus the limit is now dropped to 8600 pounds. Looking at the trailer sticker the axle itself is rated at 7000 pounds which since it is the lowest number becomes the maximum weight on that axle. Now the tires you buy may be 3300 pound tires and even though the axle says 7000 pounds it is limited to the 6600 pounds of the 2 tires. You must do this same investigation of the truck wheel, tire and axle combination.

    The DOT will check the registered weight for your tags and the weight restrictions of each axle. If the weight of the combined 4 axles is less then the registered weight and the weight is distributed across the axles and does not exceed each axle's max then you are good to go.

    Note: the ratings that the trailer manufacturers give each trailer include the weight that is transferred to the truck. That is how a trailer with 2 - 7000 axles is rated at 15000 pounds or more.This is why the long explanation.

    Unless you have some connections for getting the loads I would hold off jumping into the market as the rates are very low. In fact a lot of the loads are paying under the cost of moving the truck. But for some #### reason people are taking the cheap freight.

    Get a spread sheet and run the numbers if you get into this game. Do not fall into the trap of it was a back haul or I was getting to a better location. The brokers have learned how cheap the carriers will move a back haul so now all loads are a back haul thus rates have gone below carriers costs.

    Thanks for the info. I’m still determining if this is going to make me money only doing it part time. I’ve got a full time job and would only be doing this on my 3-4 day weekends.
    I’d like to run 3 weekends of the month so 12 days total each month. I don’t just want to recoup insurance/operating costs but also make some money. Not looking to become bloody rich off a part time gig but I still think their might be money to be had.
    I’m also out of Southern California and stumbled across the Pinnacles website who offers pay to haul RVs. They claim to have a distributor in Riverside, CA. I may look in to that also but I’m sure the pay is a lot less.

    RV pay is pretty low and most of the time you dead head 50%

    But, for part time work, and with very little investment, you could make a little side cash.

    Your insurance cost will not let you run as a part timer. And if you can get onto a loadboard you will see very few loads on the weekends. If you have a full time job find a better hobby. This is one of those games that you need to go all in to win.

    Say you do find a load and break down. You can not get up and running until Monday which job are you going to pick when your are 200 miles away from home?

    Just an example of something that might happen.

    So, let me see if I have this down properly.

    My truck tires are rated at 3,640 lbs per tire so that is 7,280 lbs per axle? I could not find the actual axle rating for my RAM 3500 but I'm sure the 7,280 lb number is lower. So I cannot exceed 7,280 on my rear axle?

    The trailer axles are rated for 8,000 lbs each so a total of 16,000 lbs can be on the trailer. The tires are rated for 4,805 lbs per time, 9,610 lbs per axle for a total of 19,220 lbs, however because the axles are only rated for 16,000 lbs, I cannot exceed that number? So, I can carry a load of 9,670 lbs? (16000 rating - 6330 dry weight of trailer)

    I took these weights from the tires on my truck and then off big tex's website for their 16GN 35+5 trailer.

    Thank you,

    Andrew

    Well, there is some transfer to the truck too, so a few lbs more will be fine. Just need to know what the loaded tongue weight is and make sure the truck axles don't overshoot that. And well, how the trailer is loaded and where that weight sits will matter too.

    Andrew, what npok is saying is coming from experience as he says. I myself have always ran under 26k. I am limited in freight opportunities. The BigTex trailer you are looking at is to big to run under 26 and to small to run over 26. IMO this trailer is not widely used for commercial.
