I still use a 1000 when i go alone because i have no hair . I use the 2000 when my DW goes along because she still has hair.
I used the honda 1000 for years on various rv converters to charge my two coach batts as well as run a separate 3-stage charger for my deep cycle trolling motor batt.
I have used both solar and genny power. I found that i got more use from the genny than my solar because i normally park in the shade or it's usually overcast or raining whenever i go. I honestly don't miss the solar because i carry the genny with me anyway.
I would probably go back to solar if i used my tc more often (full time) or if i used it in a sunny environment (western states).
