I feel ya. JK or JL regardless, what are your plans for the Jeep long-term?
If you're in a better financial situation with the JK and want to build it and use it, do that. But if it doesn't matter and you want a new project that may cost a little more, do the JL maybe.
As far as getting a new vehicle, we are in a similar situation right now. The WJ is our trail rig and we've sunk more money into it than necessary but no regrets. Our JK is really 'her' JK and that has a bunch of money in it (cosmetic pink shit). That's the daily driver. We just re-geared it last year for practical purposes. However it's at 190k and that's a lot of miles so we're considering getting a new vehicle for reliability. We'll still keep our other Jeeps regardless because I love mine and she loves hers. But as far as road trips, we've had no issues with the JK but there is still risk with the mileage getting higher.
We're Jeep people and that will be our next vehicle without a doubt. Realistically we don't need another vehicle, but the high mileage on the JK does present some risk.
