lot has to do with your incoming power. if they are running on low volts its tuff on them ,could burn a new out in a heart beat.
X2 Look at all of the discussion here about running AC with less than ideal {120 volt} AC. Smallish generators and 15 amp power cords may get them running but the low voltage takes a toll. A decent EMS will add years to the life of any AC by protecting it from voltage fluctuations.
Also consider realisitc expectaion for performance. Most RV Ac's will only get you 20 degrees of cooling vs the outside abient temperature if they are sized properly for the RV. A 13,500 BTU AC in anything over 27' is expected to do things they were never engineered to do.
The Coleman on my Nexus is 6 years old and going strong and living in southern Arizona it gets a workout on a regular basis.
As always... Opinions and YMMV.
