gastrol, IM LAZY!and having back problems, i dont like lifting too much weight and a cart is just as much if a hassel.
I hate to say it, but if you don't like lifting and have back problems, then a 10" maybe to big for you.
In your case, you maybe better off with a 6". I myself have a 10", while it is portable, it still not a light scope by any means. I used to have a 6" Newtonian and an 8" Newtonian before the 10", the 6" was light as, the 8" heaver, but the 10" is a lot heaver then my 8" was.
I would not like anything larger then a 10", just to heavy to call portable, and even a 10" is a heavy scope.
If you find yourself lazy and with back problems and find moving the 10" to heavy and bothersome, you will soon tire of the scope and astronomy in general, so you maybe better of with the best 6" you can afford.

a cart is just as much if a hassel.
If you don't have any stairs, I don't see why a cart would be "just as much a hassel". I used one the entire time I had my 8" dob, & it was so easy to slip the cart under the scope, secure the scope with a strap, and outside for viewing! I could move the scope on the cart easily with one hand. In the house, I just left the scope on the cart.

Over the years my Obsession 20 has suffered thru at least a dozen thunder and snow storms under a cover and tarp, and the movement is as smooth as one could want, the NGC MAX works great, as does the dew heater. After 10 years I did have the primary re-coated last year.
I do think it is not a good idea to let a scope stay wet under a cover for more than a few hours at most. I have two covers: one is water-proof, and the other is a white dust cover. I switch based on the expected weather.

With regards to the particle board, yes, if it gets very wet you might have a problem. But in theory it's fairly well sealed, and the condensation i've gotten so far has had zero ill effects on it. Though if you have very moist soil, you might want to put some sort of barrier under your telescope as added protection. I figure the particle board will last a very, very long time, and if it does eventually fall apart, a replacement rocker box is a cheap and good upgrade anyway.
I'm a huge fan of storing your scope this way. I use my 10" dob more often than even my small 80mm grab and go scope now. Just pull the cover off my 10", and it's already mostly equalized to the ambient temp, and you're good to go. IMHO it's even easier than a dedicated observatory, and far cheaper (as long as you live in a relatively safe neighborhood and don't stay up at night worrying your scope might walk away).

I actually saw a particle board, 16" Meade Starfinder become victim of moisture at a star party a decade ago, in dramatic fashion, with the two altitude supporting rocker boards separating, falling in opposite directions, solid tube assembly straight to the ground with a thud. Fortunately, the mirror wasn't damaged, owner muttering something like, meaning to convert to a truss dob anyway.
See what I mean?
Like I said earlier, "I can't think of a better reason to buy a new scope than that the one I have is falling apart. " :money:
