I pull my 310 Da roughly 5 to 10 mile twice a year to storage on a custom built road trailer with a 2012 sierra 2500hd 4x4. Now the trailer handles the weight and braking with no problems and the truck could care less with power even being a 6.0 gasser. The only thing that it was lacking was the truck was a little soft feel so I fitted it with Firestone HD airbags. The truck wasn't squatting under the tongue weight just didn't like how it felt rolling down the road. I'm hoping with a little bit of air in the bags the truck floating feel in the rear end will be better.
