I wanted to share a quick update on our setup of the lr3 and passport 2650. I was using the stock hitch receiver on the lr3 and it just cracked and is no longer usable. I believe it was from hitting the emergency trailer brake but I was never really comfortable with the hitch receiver because it was rated at either 500 lbs or 700 depending on which documentation you trusted.
Anyway I installed a curt hitch which is rated at 800 lbs with a weight distribution and feels much more solid. Not sure if i will feel a difference but better piece of mind. I've towed with the lr3 7 times now and have never been concerned with power and with the propride hitch I've never had any sway.
Hopefully the new receiver will make this a great setup (until I get a pickup).
