Before we bought our 80 series , we had a 06 rubicon unlimited. I liked the jeep as long as I didn't take it on the highway. Which was all the time. Because we needed more room and wanted to get into more serious offroading and expeditioning, we bought a cruiser. I have wheeled it along side big lifted JK's , YJ, etc and gone everywhere they did on 33 all terrain.
Last year, our first big trip was Moab and death valley for a month. We did around 600 miles of trails and off Roading. You know what broke ? An exhaust cushion. That's it
We have done routine maintenance , of course, and replaced the birfields , but we wheel it hard alot, in the Rockies, in the deep snow, deep water, deep mud, etc etc and it has never failed us, broke down, complained. Last year, the alternator crapped out on a trail. we got it home on battery power, and I just rebuilt that unit.
My girlfriend drives it to work every day. She loves it so much, our next one will be a 100 .... And the 80 will be used for trail only. It's one of those things where I really loved my jeep.... Until I drove a cruiser. Never looked back. Now, I'm not one to comment on the mileage , as I have a 1hd-t diesel And get 24 mpg on pavement and around 8-10 mpg off road fully loaded.
