Hi everyone! I am looking for some advice. I bought a new Sure Trac 20 + 5 7000 lb tri-axle gooseneck trailer this past fall. I am presently pulling it with a 1980 F-350 dually with a 400 gas engine & 4 speed trans. This trailer weighs just under 6000 lbs empty according to specs. I can really feel this trailer behind me empty. I hauled my IH 706 home with it in the fall & my truck sure felt that load. My question is, would I gain anything by purchasing another 1 ton with a diesel engine or do I need a bigger truck? I will be hauling 5x6 round hardcore bales and would like to know if I have enough power or need more. I figure I should get 14 bales on the trailer however, I don"t have to take a full load. The bales weigh approx. 1000 - 1200 lbs. I don"t have to haul any further than 30 miles or so. Any info & advice would be greatly appreciated, thank you.
