Do not have a Monaco, but do have a VMS 330 installed on our Newmar. Am total happy with the unit and the data it provides, would definitely go this way if I had to do it over again. Nice feature is the use of your rear camera monitor as the display. Only thing that needs to be mounted somewhere is about a 3x3 switch and touch pad. Was looking to intall a VMS 240 but finding an optiminium spot for the display was a bit of a problem. The 330 was a geat compromise and cheaper also. I have the pressure pro interface unit also so all outputs are displaced on the rear camera monitor.
