A: Hi, Dave. This model is a cold-water trailer and does not make hot water. Take a look at models 95005 & 95006 and see if they are along the lines of what you're looking for!

Q: I'm soon purchasing a simpson 3600psi/2.5gmp pressure washer. If I decide to build my own trailer with this unit and a water tank, would I need an additional pump between the tank and the pressure washer or can it be gravity fed. If so, what size pump?

Great unit. I received the MSO within a week. Registration went smooth. The Lake Havasu City, AZ store assisted with the ordering and it arrived before date promised. The store did the assembly and it was road ready upon pick! Great experience! Thank you Shane.
