Unless you live in a Hobbit house, I feel safe in saying, a 1/6 M-10 will fit through your doors. A 1/6 M-10 would be about 16" wide....not exactly a tight squeeze.
The listing doesn't say what the tank is made of. It doesn't even say if the interior is complete. With an open top, interior detail is kind of important.
AND as Pickel says, we are looking at a model of an old Sherman mocked up to be a M-10. For $5,000, I'd expect more accuracy. AND what does it weigh to require freight shipping with "crate included". That listing begs a lot of questions to be answered.
OK, the price is very high, but there are 1/6 M-10's that start around $200-400 and let you put as much detail as you and your wallet want to spend. I paid $150 for mine and will start it "someday"........ right after I get my 1/18 21C KT.
