[Jim] I have a 21' Trail-lite travel trailer that I've been pulling with a Jeep Cherokee. I just bought a Chevy 1500 with a 5.3L. My hitch has several bolt holes for height adjustment. If I can't adjust it so the trailer is perfectly level, would it be better slightly lower in front or higher? What is the reason for the hitch head to be at an angle? Is there a proper angle or is this just part of the height adjustment. Thanks for any help.
