I assume it is gas. The engines from that period were very reliable. The 5.7 might be marginal if you are hauling a heavy camper through the mountains, you might have to be patient on steep grades or pay the penalty in fuel consumption and shortened engine life. The 7.4 will likely pull anything you choose to throw at it but will require more frequent fuel stops. I HATE the 6.5 diesel.
