where you can't rely on leaving the top down - hot and rainy, as mentioned above (or below). I've used mine even with a soft-top on.
Doorless and topless are great when the weather is decent, but we road trip far to often to leave it that way all summer. 3 out of 5 days in Moab in august it was 100°+, the other 2 had thunderstorms. Add in 13+ hours on the freeway at 80mph+ and that would have been one of the worst weeks of my life instead of our best wheeling trip ever. We’ve wheeled in AZ when it was 118°, the AC is mandatory for most of our summer trips. May not need it for Oregon in May, but we won’t be doorless/topless for that trip either between the 12 hour drive, the mosquitoes, and the mud in the Pacific Northwest. Some Jeeps spend their whole lives as beach cruisers, of course they don’t need AC, but for our use it’s a necessity.I don’t think I’ve used my AC in my TJ in atleast a decade. I check it from time to time just to make sure that it is in working order, but From April to October it remains doorless and topless the way a wrangler should remain.
if you are not willing to do this with a new JL opt for the AC
