For bug in/vehicle bug out,
Coleman Dual Fuel with trangia alcohol back-up. The link is to the current model.
I think a Coleman 533 like the one you linked to makes a lot of sense for a vehicle (or bugging in). A bit much to carry though.
I'd run it on white gas wherever possible and save unleaded for emergencies only. Yes, I know it says "dual fuel," but unleaded will degrade a stove no matter what it says on the box.
