Honda generator to truck camper

I am no expert on it, but personally I do not use a surge protector between the same Honda and my TC. I usually only use the Honda to charge the TC and my AUX batteries as needed. (I don't have solar yet) I have used one of those little heaters, but rarely. Also I try to keep the Honda sheltered (at least the control panel) out of the rain, but I don't obsess about it. I am more concerned about keeping good ventilation to keep exhaust outside. And I never run it when sleeping, just never felt comfortable doing that. But being in PNW have never felt the need to run our AC overnight either. But that might change once retire and get to go desert camping!
