Any advice on 7x14 14K dump trailer for my new truck?

Thanks for the update. It would put a strain on your truck for sure but that sounds extreme. A cubic yard of road base typically weighs around 2,600 to 2,860 pounds, which would be about 3.5 yards for 10,000 pounds. I could certainly tell when I had 6 yards of topsoil, at least 12,000 pounds of material, in my dump trailer behind my GMC 35000HD with the 6.6 Duramax/10 speed Allison combo. In Tow/Haul mode it pulled it without issue, running up through the gears to 55 MPH. Stopping was my concern but that was enhanced with the trailer brakes and exhaust brake.

I learned my lesson. I now limit my topsoil loads to 5 yards to avoid any issues. For reclaimed asphalt, 2,700 to 2,800 pounds per yard, I only get 4 yards. I have 11,250# of payload capacity so I am maxed out on weight, but it is only 6 miles to the yard to load on flat Farm to Market roads, no highway travel. I also upgraded to Hartland Load Range G tires after 2 of the Load Range E tires failed after a trip, fortunately after I got home.

Yes, I think I'll do my best to limit the loads to about 8-9Klbs + the 4.2K trailer. Total of around 13,000lbs rather than the 14,200 lbs the truck is rated for. There's no point over stressing the truck just to haul a little more material.

Around town it did just fine. But that steep winding road at elevation is just not the gassers forte. The chassis did great towing that heavy load too.

My Big Tex had been upgraded to G Range tires, which was quite an improvement over E range tires. (10ply versus 14 ply tires). I had a bearing getting warm on a trip and stopped to get it replaced, and found a brake shoe that the lining had come loose on, so while fixing that...I glanced at the tire date codes and realized they were... well, OLD! So I looked at new 14 ply tires, which they didn't have a matching set, so I went up to the trailer sales place and saw a set of mounted 17.5 tires that were rated at 16 ply with the same bolt pattern as my 16 inch rims. I went on to the next level without looking back. (Good thing because I tend to carry more than I am supposed to, lol!)
Point is, next time for tires, take a look at 17.5 inch tires in 16 ply. I bought mine for just a few dollars more than the 14ply and got new rims with them. (they aren't pretty, but solid rims)
