Thanks everyone, I've narrowed it down to the 700 watt Go Power, the 600 Watt Samlex, and the 600 watt Xantrex. I looked at the 600 watt Bestek Pure, but it looked rather diminutive compared to its competitors, so I'm not sure it would have the same longevity as the other three.
My only dislike is all of the nicer units use GFCI outlets directly on the inverters and GFCIs tend to fail over time. I usually prefer to have the GFCI as an independent component that can be readily replaced if it fails.
All three have remote control switches, with the Samlex one displaying some other info aside from on/off.
They all appear to use the same phone cable type connection for linking the remote switch to the unit, I just need to confirm if the pin out on that phone cable is just stock phone line or something unique to their devices.
As, the cables listed on the remote switches are 15' long and I will need a longer one due to the route the wire will need to take to get from the inverter up into the cabover bedroom wall above the sink (Most of the camper controls are on this wall so that they're easily visible and accessible).
