Nice! Sounds like it will be ready for this season.
If money isn't an issue I would go ARB, they lock and unlock
SO much faster than the Toyota e-locker.
I have the smallest TF31 model, this was the largest model I could fit with the upper cargo rack I have in the back. Between the fridge in the 4Runner, and the fridge in the trailer (same model) I'm in pretty good shape. More room is always better, and if I had the room I would have gone with the TF41 model (I think the TF51 might be a little tall, but you can measure for yourself).
FYI - The TF31 is only $399 once you add it to your cart.
