No, I haven't seen that. I'll have to look into it, because a rack IS my next purchase for this truck......David, have you seen that FrontRunner has a rack system that mounts to stock racks? Basically you could get one rack and move it from vehicle to vehicle as needed.
Nav's not a big issue, it's just that (a) the nav is usually out of date, which requires the purchase of a ridiculously-priced update disc from Lexus (b) if the nav screen were ever to go out, you'd lose control over HVAC, Audio, etc., and (c) non-nav gives you the option of installing any type of contemporary double DIN radio.a 470 may be in my future when the seq dies. 3rd row and dvd are so appealing. not sure I could deal with smaller cargo area. Is the nav a big issue? No apprehensions jumping into one with 200k miles?
