D & G, We bought our HR DBD over a year ago and also tow a Wrangler using a BlueOx Aladdin tow bar and a SMI Stay N Play Duo aux. braking system. This set up was around $2K but after a lot of research, I felt the cost was worth it...I'm really lazy and being retired, I've just got a lot of quit in me as well. I like the lack of intrusive braking equipment in the driver's compartment...I just flip a switch after tow bar hook-up and we go...five minutes, max. This set up is easy to forget that the Jeep is back there.
If the PO has not already done so, I'd recommend adding a rear track bar to keep 'tail wag' to a minimum. With their long rear overhang, the Vacationer benefits greatly with this upgrade and cuts down on the corrective steering in crosswinds and when being passed by large trucks.
When I was looking at towing equipment, I did notice e-bay had several used tow bars for sale and if you can find one that is near new, go for it. I just couldn't bring myself to buy a tow bar and auxiliary braking system of unknown quality and so, I bit the bullet. After my wallet quit smoking, I've really enjoyed the confidence that comes with our chosen towing system.
Have fun looking for your towing system and feel free to PM me if I can help you with any questions. We love our DBD as well. I kid my DW about having two heads in the coach... "Since you do not have to go all the way to the rear to go to the bathroom, I guess I don't have to remove the front TV to install a DEPENDS dispenser as you get older"!
Now if only the bruises on my arm would heal...
Congrats on the HR and the Jeep...safe travels. Bob
