Those wheels are the same spec's as mine. I also run 275/65-18 and 2.5" level. You'll be fine with those. I had to adjust my crash bars as far forward as possible and they clear with very minimal rubbing at full lock.
Here's mine. Hope this helps.
I notice mine has swapped screens on me too from time to time. At first I was wondering why. Then, one day caught myself and I realized that I sometimes bump the button on the wheel and that's what causes it.
I'm with you. Mine doesn't do that well with MPG's either. I average around 18 on the cluster. If I do the math on my trusty phone calculator I'm around 17. Funny, my supercharged GT Mustang gets around the same. Actually my Mustang does better MPG's on the highway than my Ranger. LOL
I traded in this '05 F150 Lariat 4x4 for my Ranger. This gold one replaced my '04 green one that got lost in a tragic accident in '2012. I bought my green '04 new in late '03, so combined I had them over 18 years. It was time for an upgrade for sure. "Yep ,same camper shell" LOL
You and I have the same tastes. Here's' my supercharged '15GT. Although I still have mine. Shame on you for trading yours! LOL
I do enjoy my Ranger but I gotta have a modern V8!
