Regarding Bob Turchan's half-top
Dan's reference to the half-cover that Bob put together is a good idea, depending on the weather conditions where you live.
Currently I am residing in the south-west desert region where extreme heat and UV damage are a constant issue. And due to the fact there is not ample garage space to park all of my vehicles inside, my 'shop truck' lives out in the sun. So I purchased a half-cover like the one Bob put together for his X. It does a terrific job at cutting down the heat and UV exposure inside the vehicle. It is also easier to put on and off than a full cover. But I've realized a couple of set backs with it. The biggest one is that we get constant 20-30 MPH winds with gusts up to 50-60 MPH. Therefore the top just won't stay in place, despite adding additional anchor points and other modifications. Likewise, the wind makes it difficult to put it on by yourself (trying to put on a FULL cover is impossible in the wind). The other issue I've found is it does not keep out the dust and dirt that is excessive in this desert climate (it also might not be totally effective in keeping out rain, though we don't have that here). As a result of these issues I've discontinued using the half-cover, otherwise it should be a good option in other regions without such matters.
So I'm suggesting that you consider the conditions where you live and how you intend to use a 'temporary' top before deciding on the type/design you use.
