I've also heard that by using rollers and when they bottom out, the weight of the trailer is shifted from the suspension (that is located across a large percentage of the center of the frame) directly to the end of the frame and may cause the frame to bend. Not sure of the validity of this...

You are correct that a significant amount of the weight is shifted to the rear of the frame. I have a 34' Avion triple axle trailer that I put wheels on the rear. Very few times they have been used, but they are nice when needed. The Avion has a very strong frame. I would never consider doing what I did, to an Airstream.
Unless your driveway has a huge dip in it, there should still be some weight on the axles. With my 34' Avion being so low to the ground, I don't use it much anymore. I like to go back further off road than I can get it.
