Well - my two cents - you've asked if a 35-watt solar panel could be used as a trickle charger. I'll go with yes! Meaning - you are in a near zero draw, not using any power, the camper is in storage and you just want to prevent the battery from dying. BUT - if you expect to take the trickle charger setup camping with you, use your batteries at night (lights, pump, heater fan, etc.) then have the solar trickle charger fully charge your battery during the day so you can use it the following night; I don't think it will work. You will need a larger system (panel(s) and solar charge controller.)
