Make sure the Cherokee is a 4 wheel drive
WITH ADII (ad1 is
not flat towable).
etrailer is a good source for parts/prices/DIY instructions
There are several manufactures Roadmaster, Blue Ox, Demco… cheaper and higher priced parts.
I did a self install on everthing, prices were
LOWER in 2016 and it cost at least 2K$'s. I found our towbar on Craigslist.
If you get a dealer to sell and install expect a much bigger price.
AND make sure they/you install a charge wire from the MH to the Jeep.
The following is pretty close to our setup with 2018 prices.
Blue Ox base plate $470.
