Any LV1 and LV3 owners and/or Techs out there?
LV1 vs LV3 Pros and Cons
I know the LV1 does not have the fuel management system that the LV3 does. But I don't know if this is a PRO or a CON.
(Are there known problems with the FMS of the LV3?)

IF you have seen my G3500 Toy Hauler - you know I build odd stuff.
For some time now I wanted to install an LV3 into one of our Ultravans.
But the LV1 might be a better choice without the Fuel Management System. (But then again - I've been out of the game of turning wrenches for a living and I don't know much about the newer systems and their PROS and CONS.)
