I'm 6'5" and drive a Suburban. Even though it's a big vehicle, the cockpit space is lacking. I used to keep the seat as far back as possible and low. I mistakenly thought I needed the headroom. Last summer, I removed the driver seat to replace the seat cushion and had to put the seat all the way up to make room to access the bolts. After replacing the cushion, I replaced the seat assembly and jumped in to see how it felt. I immediately noticed how much better the seat felt raised up. No head clearance issues and my legs feel better on long rides. Thankfully, this old dog learned a new trick.
