Depending on how far you strip it down, you may not need 4 or 5 friends to help you lift the tub off... Minus wings, doors, bonnet, boot lid, interior, etc., the tub itself is not real heavy. When I was about 24 I carried the tub of my TR4A about 100 yards by myself to get it into the barn. Oh yeah, the windscreen was off too.
The last time I had it off, my brother Jim and I did it with all the winds, doors, lids etc. still attached, but we used a hoist that time.
It's pretty easy really.
