Question is would it be a good TV to pull a 5er weighing 14800# with a TW of 2850#.
It looks like I would be within the manufacturers recommendations.
Am I missing anything that should be a concerned?
You will have a severally overloaded 3/4 ton truck.
Your basing all your numbers on the trailers dry weights which is unrealistic.
The trailer shows a 16490 GVWR vs a 14k dry weigh.
Now lets look at reality.
Your going to add another 1500 lbs at a minimum...most likely more to the trailer. So now the trailer weighs 15500 lbs.
Pin weight will be in the 3100 lb range. Add 200 lb hitch/350 lbs for occupants/100 lbs of necessary junk in the truck ...all adds up to around 3700-3800 lbs.
Now lets look at the 2500 truck with the small 6200 RAWR which includes wheels tires and rear spring pack.
Using GM online ordering guide weight calculator that figures all the options and std weights for each GM truck shows a TC25743 Serria Denali 2500 Dmax/A 2wd std bed crew cab has a 2704 lb payload.
Your going to be 900-1000 lbs over on RAWR when the truck and trailer is loaded and road ready.
If you take the truck in for warranty work or service I sure wouldn't tell the the dealer your overloaded. He can void the new trucks warranty.
A 15k trailer can really push the back end of a 250/2500 truck around especially on twisty winding roads and in strong side wind conditions.
Load the combo up and get some front and rear axle numbers. Then you will know for sure what type mods you will have to do to the new truck.
