We have a Coverking custom cover (silverguard) for one of our cars that's kept outside all the time, great fit and it really keeps the interior cool. We got it through Costco a couple years ago when it was on sale. They do make one for the Comanche, but pricey. https://www.coverking.com/uv-protection-silverguard.html?noforce=1&nopromo=1#select-vehicle
