Not really sure, but they put it on alignment rack. They installed adjustable track bar and steering stabilizer for me with kit. Made it a point to show me how adjustable track bar only moved front end about 3/16 of an inch. Not sure if any alignment adjustments were made, but know they checked it.
Heard you mention living in hilly areas. Also mentioned a generator and solar. After your fully loaded with family and equipment, you will be maxed out with the XLS21. I had a 22' trailer that was 4100 dry. About 4600 as I towed it. Around 600 lb tongue weight. In the hills of WV with 35" tires...
3 months ago I had Mopar on the phone and they quoted me 7 years/ 100000 miles for $3200!
Told them forget it. These prices look much cheaper........confusing.
Here is almost $8000 off a 2020 Mojave. This is where I got my JT.

You could take it off with hoist. Would need to make a quick disconnect for the 12V light, and would need help. It's 130 pounds. I never have my hardtop off, but yes you could remove it still.
Yeah I put the Terraflex track bar on. Mechanic who aligned my front end said it moved about 1/4 inch at most. Knowing that I probably wouldn't buy one again. I think the stock would be fine. But if you get one at least it's there if you ever want to go bigger.
