yup, its a cross roads for sure, take it from me, i also have a sidekick, duals t case, toy axles 37's exc exc......
but it gets a bit harder to just "pack the kids up and run some trails" with a rig like that.
so we put 33's on the xl, but dont want to destroy it off road either (body wise anyway)
keep in mind, the better you build it for off road, the worse it will be on road, and its finding that sweet spot thats the problem, for the most part that line is at a 31 to 33 inch tire, after that the fun starts to get taken away with bad on road manners and equipment failures lol
that and the hobby changes a bit as well I find. when every trail you want to run is almost guaranteed body damage of some sort, and things of that nature, is a bit different than running a few somewhat bad trails to get to a nice camp or picnic spot, if you know what im saying, just take a hard look at what you enjoy most about 4 wheeling before you cross a line of no return, to build a truck that can do things off road that you don't REALLY enjoy as much as what your doing with it now.
if that makes sense lol
