Does the CHassis system have outputs in the back or mid area of the MOHO like a big conversion van??? IF YES, this is typically a point of failure because the refrigerant lines are not factory engineered system but rather a cobbled together addition to the factory system/lines and are often not as well engineered as the factory/chassis system... They are add on's to the factory chassis system...

IF NO, if the chassis system doesnt have additional rear cooling i would suspect that your compressor is just fine since it's only 10k miles... I have had the factory compressors go over 200k miles and work just fine...

In front of the radiator there is a condensing coil that is another common point of failure in those unions/connections... Most of those unions have dual urethane (green) o-rings and are typically pretty rock solid but minor front end damage can easily mess up that condensing coil and unions...

When the system is running look at the dryer/evaporator core area (see picture below) to see if it is frosty white/freezing cold... This is often a indication that your orifice/aperture is plugged (easy fix)... The big black can is the dryer and has the pressure switch attached...




The orfice (see below) can be located in a few different places and will require you to do some online research to nail down its location... Sometimes located in the high pressure line a few feet from the firewall and sometimes located right on the inlet to the evaporator core unions (on the firewall)... If this thing gets plugged it will cause your system to malfunction, usually they are plugged on older/high mileage cars/trucks or contaminated systems...
