well, i don't have either one on my truck; however i do sell both of them at the store that i work at. i'm not sure why, but i sell the crap out of the truxedo, but not much of the access. i know that the truxedo sits lower, and that the release handle is a little nicer. (although i still have the '08 floor sample, they may have changed the handle on the 09's)
i've never had to warranty either one of them, and i've never had any complaints about heat before. id worry more about ice than heat in all honesty.
good luck!
post pics if you get something!
