Not a bad solution but many CA airports do not allow owners to bring their own fuel tanks/trucks onto airport property—liability reasons, supposedly. The truth is probably that FBOs and fuel vendors don’t want to allow anything on field that would cut into their sales.
100LL is on its way out; no matter what its real hazard to the public (minuscule), there’s no doubt that use of leaded fuel is terrible optics for GA. That ship has sailed, and logic simply does not apply. GAMI’s G100UL is already approved by STC for all reciprocating engines and the roadblocks put up by entrenched interests at FAA and in the avgas industry need to get out of the bloody way.
