Just a few modifications I added to our new RV.
Took the advice and installed the Oxygenics Showerhead
Added a wireless router that will allow us to have our own network and connect to the campsite network. Also added a Roku that connects to the RV wireless router. We use the Roku to watch Netflix and other online content.
OBDLink MX to monitor the engine, gas millage etc. This is the Bluetooth version
Torque monitoring application on my HP Slate 7 tablet for the OBDLink MX
LED light bulb replacement for the shower - bought on Amazon
LED Lights throughout the coach
