sir @pwuser155776992719 there is negative 5 possibility to find an LC80 series or an amazon variant totally stock with clean papers.
over the years reading about land cruisers at Japan LC development site i can carefully tell you that the trim levels and the dual tank are not offered as in a single package.
Dual Tank basic LC 80s & 200s are supplied only to UN in ambulance & basic 6 door (rear door dual hatch) version as UNHCR workhorse in East African territories only.
For every other variant Dual fuel tanks are offered only by after market retrofitters doing customization of SUVs.
so sir either you have been misguided about the Land Cruisers or you have not done enough home work for your requirement during proud ownership of 3 LC80s. May be your passion is only to ride and be proud. rest is assigned as job to your paid employees.
