I'm not about to knock the Oliver, a great trailer.
About efficiency, that depends on your definition (of what is is?)
In terms of the trailer battery
, my arm is infinitely more efficient than the motorized jacks. Just a different perspective. And regarding LEDs,it's now possible to switch out all bulbs on a Casita
for well under $50.
But the fact that Oliver installs 4 batteries and 320 Watts solar
, even with LEDs, shows it's in a whole different category electrically than Casitas, Scamps, etc.
I don't say that's bad any more than I say Airstreams are bad. Just that in some ways they are in a whole different category, electrically, efficiency, and cost-wise.
I might be tempted to say the Oliver is an Airstream in fiberglass clothing.
