I emailed Newell this morning to ask what brand they recommend. I'll post it when I hear from them.
Some Prevost friends of mine use the Progressive model that plugs into the CG power outlet, but they have had trouble with this unit. It would give false readings, not connect, etc. Progressive would always replace defective unit with a new one and over time they would find one that would work. Hopefully I can find a brand that gets it right the first time.

Has anyone used this brand?
