What is your driveway like? Paved or stones? How much height difference between driveway and garage.
My drive is paved and I have about 1 1/2in step up from the driveway to the concrete floor of the garage. My machinist friend told me "no problem" - and happy to report he was correct.
I just needed to use a few pieces of black iron pipe. We used an engine hoist to get the mill from the trailer onto the pipe on the driveway, we then rolled the mill on the pipe, relocating a piece of pipe as it became free from the base.
Once we got to the driveway, I put down a piece of plywood, so we cut the height difference in half, then tilted the mill back to get the front of the base onto a piece of pipe on the plywood, then continued until we got to the concrete edge of the garage. Then tilted back again onto a piece of pipe on the concrete. Then continued.
You will need two people to do this safely for the tilting, also for the extra muscle. It can be done.
The benefit of floor standing is not having to lift the machine onto a bench. Never easy.
I wrote this then realised I missed the part in your reply where you have to get it into the house first, then the garage. Drat, not as easy as it was for me with access directly to the garage.
