Question:
Hi Folks, Im looking for a cargo hitch hauler for my 2021 Jeep Wrangler Sahara Altitude, 4 door. Tire size is 255-70-18, factory. I have 3 1/2 from the bottom of the spare tire to the top of the 2 hitch. I would like to be able to open the rear door with the hitch installed. Although not critical, I would like it to be folding. I also dont mind if I have to install a 8 extension. Size doesnt matter, but prefer the biggest. Aluminum would be ideal. Thanks, Anthony

Hey Anthony!
For your setup I recommend using the Swagman Swivel Hitch Extender # S86SR. Not only will this extend the cargo carrier out past your spare tire, but the swinging arm means you don't have to unload your carrier just to open up your rear door.
Then when it comes to an aluminum carrier we have a few options; the 22x60 Flint Hill Goods Cargo Carrier # FHG49ZR is my favorite for a standard carrier, but for a folding carrier we also have the 39x25 Inno Quick Base # IN92RR.
What are your thoughts on using the swinging extender arm?
