I guess one BIG plus to this would be the fact that you can use the trailer jack to raise or lower the tongue to get the deck perfectly level. Dang it. Now you got me second guessing this. Lol
There are more upsides that that setup then that
For starters, think of how easy it will be to move that around the shop, compared to 700 pound ramps
Even bringing it home is a one man job
