I tow a 295RL and you will be disappointed with both the performance and fuel mileage of a 3/4 ton gasser. You will almost surely be over the GVWR on the rear axle too, but might barely squeeze by. I know as I towed mine with a 2010 F350 with a diesel. Your GVWR is 10,000. Your towing capacity means nothing. What means something is the cargo capacity. The pin weight of your fiver will be at least 2000 pounds, probably more. Do yourself and your wallet a favor; buy a 350/3500 diesel. You'll never regret it once you pull you Columbus. I know. I just upgraded to a DRW 3500 RAM as I would've been overweight on the rear axle with the addition of an aux fuel tank, W/D and a gen.
