25k hours on a RRE is going in to the world of the unknown.

I've asked around my colleagues & once an RRE gets to about 17k hours you expect to start seeing big repairs / bills to overhaul things like masts etc.

I would advise try & trade them in before the big bills / repairs are required.

Everything has a service life & things wear out requiring replacement or overhaul.

FWIW the newer RRE are more bulletproof then the original ones.

RRE has just had another design overhaul, new Clearview mast designs & other general all over tweaks, i think this is due for January 2017 production - it was on the Toyota stand at IMHX a couple of months back.
