My first and only truck mount is the
Prochem Peak. Purchased it in 2005 from Michigan Maintenance Supply, currently at 5900 hours and runs strong just like the day I bought it. We keep it serviced well and change oil every 100 hrs or less.
Overall unit has been rock solid and most minor issues we were able to handle ourselves. Our purchase from Michigan Maintenance Supply was a great decision. Mark, the owner always will take my calls (2 or 3 a year maybe is all I need) and walk me through any issues I am having even though he is 3 states away. They are a solid standup company and have treated me good from day one.
Two months ago we had Pemberton's Team do some technical work ie replacing pump seals, rehosing/rebuild corrosive parts chemical injection system, rebuilding waste pump outs. We could've done this too but decided to have them handle it this time. Their maintenance guy is also well versed and is very knowledgeable and did a very good job.
The Prochem Peak has taken care of us very well, made us a ton of $, and I look to keep milking the cow until it expires! Great Job Prochem!!!
