Marvin and Precision RV are absolutely the best of the best. We are full time working professionals traveling in a 40’ fifth wheel with a residential refrigerator. In a nutshell, we are consuming a lot of power! We researched a number of other systems and never thought we would find one to fit our needs. Marvin introduced us to the perfect combination of panels and battery capacity that we knew would meet our lifestyle needs. We were completely sold when we saw the quality of Marvin’s work. It is meticulous and immaculate! I would challenge anyone to find another installer with the attention to detail that Marvin has. We are living the dream, powered from the sun, with all the conveniences that we had being plugged in – even air conditioning! So happy we chose Precision RV!
