Thanks for all the great info guys.

I decided that while the R/T would be fun, it would somewhat impractical for
me right now. Also the one I saw had low miles and should be taken care of
better than I probably would.

So, I decided to get a 04 Grand Cherokee. It's a Limited, 4.7l, with QuadraDrive.
Seems like a pretty nice vehicle and, while not as useful or fun as an R/T, it
should be OK. Call me crazy, but I've always wanted a QuadraDrive vehicle
since I first read about them.

From what I read, the 545rfe should be better than the 46re but it has the
same sensitivity to fluids (as do the transfer case and differentials).

I have to remember about putting in neutral for a bit before drive. Probably
hasn't been done until now, but at least I can start.
