I've owned an 03 Sport, an 08 SR5, and now a 2017 SR5P over the past 11 years and never felt weird about upgrading. I'm loyal and love these trucks, and when I'm ready for something new, I've upgraded and stayed with what I like. The best part is, 90% of the parts I took off my 4th gen can go right into my 5th gen since they're built so similarly. It's understandable that you're feeling weird, but don't, at least you're still looking thinking about the right kind of vehicle and not a jeep or minivan :fish:
