Will it fit with my side steps?

Not with AMP steps. There's only about 0.8 in between the tank and the body where side steps mount. Text photos of your setup to (619) 812-1903 and we'll check.

What are inboard hanger holes?

Factory mounting holes under the van. Confirm your van has them before ordering.

Will it freeze?

It's mounted outside the van, so plan freeze protection if you camp in cold weather.
