You won't have any problem towing 5000 pounds with the H2. I poicked up my Scarab in Lousianna with my Mercedes ML 360 (6cyl) and drove it to New Jersey with no pulling problems at all.
Your trailer might have Gravity breaks. If so there is no special hook-up.
VERY IMPORTANT: Make sure you grease the Trailer's tire bearings before you leave on the trip home. If you don't and a tire locks up it could be dangerous not to mention cost you time and cash! I tell you by experiance! It cost me $950.00 to fix on the way home from picking up my boat!
