I'm running a Skyjacker 4. 5" lift and tow up to 7700 lbs. with a standard drop hitch (8"-12" depending on the trailer). With an adjustable height hitch and/or an adjustable tongue on the trailer you could probably make up for 4"- 6" inches of lift... I am considering changing the front of my utility trailer to an adjustable channel type, but haven't done much research yet.
