My burb is almost up and running with a side saddle tank setup.
I really wanted to keep spare tire underneath rear.

It's not as safe as between the rails and is also a pain to route dual tanks.

There's about 9.5 inches of space between the doorstep and frame on my '59 and the biggest tank I could find for that spot is a 10 gal marine tank.

Original NAPCO tank on the other side is 15gal rectangle.
