Idea #1 A hand trolley. I use one for my ten incher but the base part maybe doesnt extend far enough to support the scopes base.
#2 Use a two piece wheelbarrow handle arrangement like whats on my SDM. The 2nd piece slots into the tubing of the mounted part, which can be easily removed as its held on with eye-bolts. The wheels dont get in the way so i dont bother removing it.
