can't recommend a shop but I will put my 2bobs in.
biggest cooler you can get on it.
warranty, who will give you the best and how easy is it to get it to them.

if you don't go local you pay all labour to remove/refit + freight incase of warranty, if interstate shop give this included get it in writing.
and then the risk of them saying it wasn't installed properly.

just something to check over with shop before you commit.
