Welcome to the forum, Sweetlou.
The flip kit from etrailer works well, according to the folks on this site, that have done the flip with one.
It's doable in the driveway if you have something to support the camper and a basic tool set.
While your in there, I would suggest you also do a wet bolt kit, it includes bronze bushings, shackles that are about 2 1/2 times the thickness of the OEM and the greasable bolts.
An '05 is likely to have nothing but a sliver of the plastic bushings left in the spring eyes.
When I was a kid I was going nowhere fast, now I'm an old man I'm going everywhere slow.
