Well, I'd say the word "cumbersome" is relative. If you're trying to do it alone I think most guys would just take a look at the thing and say "well THAT's not going to be easy to do by myself". It's not heavy but it's large & akward, maybe Shaquille O'neal could just grab it & pull it off but *I* sure can't. One man CAN do it alone but yes, it's cumbersome. With one other person to help it's downright easy and with two people to help it's actually effortless (well, effortless for ME anyways since I'll just stand back and tell the other two how to take it off) and with three people to help it's a good ole' time because while I'm telling the first two guys how to remove the top I'm sending the 3rd one inside to get me another beer.
A lot of guys rig a pulley to a joist in the garage and pull it off that way and having done that at my last house I can attest that it makes the one-man version a whole lot easier and I've also seen pulleys mounted to tree branches & A-frames so there are a number of ways to easily fab something to help pull the top. The garage method has the advantage of also being usefull for storing the top as long as you rig it well when removing it and ***** in a cleat for the line somewhere nearby.
