Any Differences In The Transmission, Manual Transfer Case 06 To 09

[Gerald Brawley]

I currently own an 06 470 GX which I tow and have towed behind a motor home for over 3 years. I know it is not reccommended but know at least 6 to 8 others who are doing it with no trouble. My question is I wonder how much longer Lexus will continue to make the GX with a manual transfer case. Am considering an 09 and wonder if there is any difference in the two, they dont look any difference.

Does anyone also know when they are going to change the GX as I have seen the Acura MDX is no longer towable.

Appreciate your feedback
