The set is awesome and I think we've been waiting for a decade to have someone do these so than you.
The one thing I'd say to try and incorporate in your next set would be to have the parts fit together on natural seemliness as opposed to the model split down the model. You did this to the crane truck and it was a huge improvement.
I stumbled upon this thread doing a search for Sacramento. I've got a big house and a 65" plasma but I doubt anyone wants to come up here. I'm East of Sacramento on the way to South Lake Tahoe though.
The truck looks great. If you actually come through with these it'll be the end of a six year wait for everyone.
Is it safe to assume the truck will come in pieces for the lift part?
