Aftermarket aux gasoline tanks still have meet all EPA (and CARB in affected states) evaporative emissions standard which usually requires installing a larger Evap system. Not all trucks have the ability to be expanded, wether hardware constrained or software constrained. So... it's a lot of work to make fullly compliant system, limiting availability. Aux gas tanks also have a stricter drop test requirement, and anternatice placements on under 8500# trucks also require crash testing.
