One of my summer projects was to make a box to store / transport the (enormous) 178mm ED APO optical tube. Here's how it turned out. It's 6'6" long, but fits into my (also ancient) '99 LS400 with the passenger seat down. The wheels do come off.
A few times recently I have gone with the Vixen to a local graveyard to observe (it has fewer trees). Not sure if I want to be seen carrying this around though "It really is just a telescope officer!"
