I'm wondering where is the most convenient location for the light switches that control your outside porch light(s) and the interior cabin ceiling lights? These are not switches for reading lights at the head of the bed.
At first I think they may be most convenient to be near the door handles. Easy to reach if you are entering or getting out of the teardrop. It might be an uncomfortable reach if you are in bed.
A second idea, which I think I saw someone here do, is to have the light switches above the door, or even in the ceiling above the door.
My teardrop will be a 5'x10 Benroy. The opening (door handle) side of the doors will be about 56" from the inside front of the cabin. The light switches I will use are Frilight Dual Euro 48602 Rocker Marine Rocker Switches from SailorSams.com. For porch lights I'll probably use small LED License Plate Lights from DelCity.net.
