The how come you dont see any around?

I have been looking for another 350/700R4 full load Slilverado for over a year now and either they are rusted far beyond repair or they have been hacked up. I see lots of full load trucks but always missing A/C or windows and locks?
BTW I pick this one up on Sunday.
