Also since you dont have a dually i would back the 1st vehicle on and drive the last one on. That way the weight is over the trailer axles and it cuts down on tongue weight
Congratulations on the trailer but 2 things you need to make sure of, you will need to have a DOT medical card now because the trailer GVWR is over 10,001 lbs. Not sure what the GVWR is on the Chevy 2500 gas truck but make sure when you add truck and trailer GVWR together you are under 26,001 lbs total.
