Cathy, IF there was info about the original utility setup for the Love Bug
, you would have the option of using that as a rough guide or blue print. As this sort of information is pretty scarce in original brochaures and even instruction manuals, you might examine the setup on a trailer of similar size and age such as a U-Haul
I understand that you'd rather "get er did" with some concession to the length of human life, patience, and energy and the above approach might be protracted beyond the acceptable deadline for interior insulation and finish. With that in mind, here's my take:
Many small trailers "build" their electrical
system on a combination of AC and DC power. The "base" level for illumination purposes is almost always the DC battery-powered system with a provision for recharging by several methods, most of which you know. I'd say plan your light system around DC only. The low wattage requirements of LED fixtures and LED replacement bulbs for incandescent fixtures have given DC a new lease on life in terms of a minimal energy requirement which stretches the time to recharge on the house battery
. DC is also the optimal choice for powering a roof fan (always available/acceptable energy requirement). Water pumps and full-time blower motors on furnaces are the other customary DC powered devices.
Beyond this is AC territory. A shore power umbilical and a barebones fused powerstrip would be a minimum. I would suggest putting at least two duplex receptacles in a small trailer--one front and one rear where conventional AC lighting
fixtures as well as small electrical
appliances, chargers, radios, etc. can be used or not used with some flexibility.
I can't remember if you removed a converter/electrical service from your LB. I personally believe that a power distribution panel combining circuit interruption for both AC and DC with the DC power-supplying and charging function of a converter is desirable for reasons of safety and transparency of wiring conventions to third parties (RV repairmen, future owners). You might look at the Progressive Dynamics PD450.
The real answer to the limited power of a DC battery
is the conservative habits you've learned tent camping. I believe the additional weight
of a solar panel
is worth the trouble. The weight
of even a small genset and fuel combined with the operational, maintenance, safety, and social complications thereof don't make it a very desirable "accessory" energy source imo.
