You don't really flip the axles - you just move them below the springs.
I did it after I got my TT, and I have never regretted it. I gained at least 5" of clearance, and there have been many times I would have hung up the trailer (or plumbing for dumping tanks) if I hadn't done it.
I believe the kits (1 per axle), Dexter brand, ran me about $80. It took some jacking, blocking, grinding, cutting of old rusty bolts, a little welding, and a few bad words, but I got it done and I love the results.
When I have to set up at a site where the wheels on the door-side of the trailer have to be blocked up to level the rig, then the first step can be kind of a pain. A small step to place on the ground nearby would cure that.
I say - move the axles below the springs. Then, as Cal said, he won't have all that stress placed on the frame from those rollers/bumpers.
I have a friend with rollers on his, and they keep getting torn up. That's another thing to consider... maintenance on them.
