Welcome to Allpar, Fleet. I don't understand why it would be any more trouble to change the doors on your Intrepid than it is on any other car. Of course, they weigh more than on a Geo so other compact. Basically, all I've ever had to do to replace an entire door is remove the hinges and wiring plug and take the door off. Of course, it helps if you have an assistant and a couple of jack stands too. Putting the new one on is more of a pain, as you usually have to make a few adjustments in order to get it to open and close properly and not have any air leaks.
