Steve yes it is a motor home. No it does not have any but the dash air 
nothing in the rear. The compressor stays on when i turn on high air does 
not recycle. When I charged it last year i put in three cans after 
vacuuming the system. It had sat for 5 years before i purchased it and 
system was empty. I purchased the charging kit that said it was acceptable 
for changing from R12 to the 134. It worked ok last summer what little we 
used it now not what i would call great.
