    Hey guys. I run hot shot with a 2008 Gmc dually. My rear axle is rated to 8200. With just a Chevy s10 centered on my trailer (40' goosneck) I was at 8000 on my truck rear axle. That makes me pretty nervous being that close to the rating when my trailer is barely half loaded. Is thier anything that I can do to help alleviate some of the tongue weight or even increase my rear axle capacity? I see people running 3 car slants with a similar and can't figure out how they are staying within the axle ratings.

    Thanks for any help guys!

    Where did you get the info that the rear end was only rated to 8200#? I am not sure when GM changed the rating on the trucks but my 04 GMC was rated at 11,400 or 11,500 and the new GM's are 13,200. Look at the plate in side the driver door. From your picture move your load to the rear of the trailer. If you are unsure of the laws of physics Google 'levers' and study the length of the lever in relationship to the resistance. If this is unclear let me know and I will be happy to help you get a handle on the laws of levers.

    Gross weight of the truck is somewhere around 12500 rear axle is only 8200 per the door sticker. I understand how leverage works but I would like to haul more than one item at a time. Meaning something will have to be infront of the trailer axles.

    A 2 ton dodge is rated at 13,500 for the rear axle. You are not going to get close to that with a 1 ton truck. You are pulling a lot of trailer with that small truck. The three car wedge is going to be much lighter than your trailer by thousands of pounds. Also the axle placement will be a key in the weight distribution. Here is a photo of a loaded 3 car wedge and you can see the last pickup is behind the axles. This acts as a counter balance to lift some of the weight off the tongue of the trailer.

    Ahh that makes more sense looking at the picture now. Id bet if they take that last truck off he would be over weight though. My plan is to buy at ram 5500 a year from now. Just hoping for some good ways to help balance loads until then. My trailer axles are pretty far back.

    It still seems like he gotta have a lot of tongue weight on that though. Those first two truck probably weigh 10k combined all in front of the trailer axles. And only half of the weight of the 3rd truck is behind the trailer axle working as a counterweight.

    I understand that. I drove a dodge 5500 for 1.5 years pulling a 44 foot PJ Trailer gooseneck. I was able to gross 42k because the axles on the trailer were rated for 24k. Could never get all the weight up on the steer but the one time I was pulled over and put on the scales I just barely made it... LOL

    Steer 5,500
    Drives 13,360
    Trailer 23,980
    Total 42,840
    Licensed for 43,000

    Can't get much closer than that.

    The weight of your trailer is what is killing you on your weights. On that dodge, I scaled out at nearly 22k but we also had a cage built on the trailer.

    I'll have to scale when I'm empty in a couple days and see where I'm at.

    His trailer probably weighs half of what yours does. And you can figure nearly half of the middle vehicle is on the trailer axles. Actually the rear one is just slightly ahead of the center axle with the front tires so most of the weight is going to act as a counter balance. Also with the slope of the trailer the rear axle of the truck is going to be heavier than if it was on flat ground. Just gravity doing it's best.
