Portable Truss Reflectors?

I just saw an ad for a 12.5" f/5 Truss Reflector and had a few questions.

Compared to sono tube based Reflectors, how much aligning/colmination is necessary after the Truss arms are reconnected? Is it even close?

Does ground temperature effect the main mirror?

Are special light shrouds needed when viewing in light polluted suburbia?

Any other things to look for in a Truss Design?
