attaching legs to a door sounds like overkill. For many years I had a door on top of 2 sawhorses. Easy to move. I used an indoor door so lighter than an outdoo

attaching legs to a door sounds like overkill. For many years I had a door on top of 2 sawhorses. Easy to move. I used an indoor door so lighter than an outdoor door. Had no issues. IIRC I put cloth over the sawhorses both because the door sat better on cloth and because I could arrange the cloth to cover the end of the sawhorse sticking out to avoid spliters.
