Gents, I’m blasting this out to all the places I know and trust looking for feedback before I make my own decision. Saw this on Facebook from a brand and user I’ve never heard of but, it doesn’t mean none of you haven’t. I won’t bury the lead. Here’s the link: https://helivuedesign.com/products/2024-current-toyota-tacoma-auxiliary-fuel-tank-system-18-gallon I know many of us are waiting for Long Range America. I’m sure we all have questions. They’re taking Preorders but i didn’t see anything on potential shipping date. Anyone have any faith and confidence in this brand? What do you think of the price? Is an 18 gallon aux tank reasonable? Any clue what size LRA might build? Here’s the info from the site and photos: “Helivue Design offers a no compromises approach to auxiliary fuel systems for the demands of the Commuter or hard core Overlander. This tank has been thoroughly beat, bashed, landed on and driven from 5,000-13,000 feet regularly without failure.

My stock wheels and spare are 245/70/17. I since upgraded to current gen Sequoia TRD Off Road 18" wheels with 265/70/18. What would be the equivalent tire I can get to run the same diameter as my new wheels in case of emergency and I need to use the spare? Also would it fit in the original spare location?

Thanks in advance.
