So let me start off by saying i am 6'5 185 and the RL is the most comfortable car i have ever owned. The last car i had was also a TSX (06) and before that was a 2000 TL. Between the TL and the TSX the TSX was more comfortable. Coming from an Acura i wanted something that rode as good as the TSX did. The closet thing i could find truck-wise was the Canyon. That was until i looked at the RL. I am amazed how you find the RL is so uncomfortable for you. I think its much better than the TSX and TL combined. My dad has 3 herniated discs and he finds the RL the most comfortable on his back. So, for me to hear that you find it uncomfortable is beyond me. I am sorry to hear that.
