Hi Dave, and thanx for posting a question which yielded so many informative answers. Will just put in our 2 cents here. We are finishing up our 3rd year full-timing in our Scamp
13. Our electrical
usage is low also - some 12V lights
in the process of "morphing" into LED's (no heater or fridge) for those a small solar panel
(UniSolar) keeps the battery
topped off. We recharge the laptops & cell phone with a motorcycle battery or a small Radio Shack inverter in the tug while driving.
While we have discovered the joys of electrical
hook-ups, we boon-docked at Quartzsite for extended periods during 2 winters and will continue dry-camping wherever we find a lovely, accessible spot to camp. You mentioned wiring your Egg without 12V - we suggest not closing that door just yet. The more you enjoy getting out with your trailer, the more you might be drawn to explore unimproved camping areas. Oh, yeah, did I mention ... we LOVE solar! If you decide to consider this power option, you will find LOTS of terrific info,knowledge and advice among the members of this forum.
Whatever you decide, we wish you safe journeys and many, many happy memories. Regards, L 'n D
