Great Place, Tremendous Staff

Sergio and a new young man, I think George, sorry if it's not the correct name. were two young men who helped me first on Saturday then Monday. Very friendly a ready to help and give advice. I drove from San Diego area to go to this business because of the great service and advice they give. Tom the manager is a great guy also. I am a retired school shop teacher and do a lot of volunteer work for youth organizations. People like this help make the job a lot easier. Thanks guys.

Eric B. (Azusa, US)
Works well but changed fitting

Works great and quality is good. Only frustration is they changed the outer diameter of the fittings and they barely fit through the passages drilled in my trailer (which is also a pacific trailer). It somewhat crushes the light wiring, hopefully it doesn’t cause lightning issues down the road due to compromised wiring.
