The idea of a space truck is not a bad one: a better one is a semi-tractor trailer. The semi and the trailer are seperate, with separate delivery systems, which is what we have been talking about for a while now in this thread.
As far as retrieval of space cargoes is concerned, there ARE ways to do it: a (fairly) inexpensive RP or robotic Aeroshell to recover cargoes is a practical way of deorbiting satellites for repair or refurbishment.
Something has to be said about the way we currently get our spacecraft back: we do semi-ballistic or ballistic re-entries when we really do not have to. Yes, they are "elegant" from an engineering standpoint, but they are brutally unforgiving of hardware and software (navigational) failures.
NASA should spend time looking at non-ballistic orbital insertions (i.e. launches from high flying aircraft, Like Spaceship One, and the Pegasus Launch System), using longer deorbit burns for low to mid supersonic re-entry. With such a scheme, the use of exotic heat shielding materials could be lowered or possibly even eliminated, while increasing safety for crew and cargoes.

Anybody seen "Morons in Outer Space"? I've seen bits and have recorded it ... hilarious. I've got to get around to watching the rest of it.
