Thanks for responding!
The LP gen is a 3.6 kw.
Carrying portable tanks doesn't work as we don't tow anything with this unit and I wouldn't carry them on the rear.
The space where the current tank is located would allow for a larger diameter, but not longer. I haven't been able to find a supplier for larger diameter tanks. They are available, Wanderlodge used a pretty fat, but short tank.
Foolishly, I didn't want a 'noisy' diesel generator again, not thinking about run time on LP.
