My Benz has cooled seats but I haven't had occasion to use them yet. Its not possible to add cooled seats without running new ducting for your AC...with all the work involved you would be better off just buying a new truck. I believe you can do the cup holders but those suckers are pricey and have a high fail rate. IMO I wouldn't bother just use a remote start to get the AC flowing or move somewhere less hot.
There are plenty of people who are tearing the inside of their hoes apart to put dynamat on them. Not that huge of a chore. How hard can it be at that point to run some pre-fabbed factory ducting??? That whole "buying a new truck" thing is a little extreme.
