The install was very easy for the average do-it-yourselfer with common hand tools. We elected to solder all the connections for a trouble free system which added somewhat to the time but the total install took us almost 5 hours - the bulk of which was used removing/re-installing the enclosed underbelly in our Wildcat 29BHBP.
Overall this is a great system with external sensors that read 0-100% - no more dirty sensors or Empty 1/4, 2/3, Full indicators.
