Prices are relative to ease of use and how well the product is made imo... at my stage in life, and for my intended/needed use. And I figured to start with 2, that's 4 gallons. If I like them a lot, I'll add 2 more. And yes, I go that far off the road.... because I'm off the road sometimes for a week or two at a time. No disrespect taken.... you don't know my needs. That's all. Plus.... while I'm in Mexico, if I can have an extra 4-8 gallons on board, it saves having to put the Mexi gas in.... on short trips (I live down here... and if I want to go do a bit of exploring.... it's easy to go through a tank. And I'm back and forth from Encinitas to Northern Baja all summer/fall. Live both places.
So. Back to my question. Has anyone used these?
