If you decide to purchase an air compressor, make sure it is an "oil free"  
compressor.  I wouldn't want oil from a "wetted" compressor cylinder in my  
water lines.  I bought a 120 V Campbell/Hausfield oil free compressor  from 
Wal*Mart (approx $100),  I carry it with me while towing the  trailer.  It is a 
little slow, but is OK for airing the truck (70 PSIG) and  trailer (60 PSIG) 
tires.  I also use it to blow out the trailer water  lines.  A compressor with 
more CFM would make the job easier, but this  compressor does the job.  If I am 
leaving the trailer where I expect near  zero temperatures, I also add 
antifreeze after blowing out the lines.  I  like to blow out the lines first, then I 
pump an excess amount of  antifreeze through the lines, catch what comes out of 
the faucets and add it  back to the pump supply without being concerned about 
too much dilution of the  antifreeze.  I think everyone is aware that you 
should only use camper  antifreeze (it is food grade propylene glycol) instead of 
automotive antifreeze  (it is poisonous ethylene glycol).
