Depth of subfloor on a TD build

[western traveler]

I am not building an off-road TD but want to be able to cross a dry wash or small swale if necessary even a bit of water heading into camp.
What is a safe distance from the ground for a storage compartment to extend below the frame in front of the axle? My first thought is no lower than the axle extends but I am concerned with uneven ground. Should it be higher than that?
I am planning on 15” wheels and a Dexter torflex axle on a 10’ build.

What is a safe distance from the ground for a storage compartment...

I considered putting the battery below the floor --near the axle-- with this last build. But sooner or later...



I hate the off-road word. It means a lotta different things to people. Off the highway? Or on a BLM two-track? We don't do what I would call "off-roading". We're always on some kind of road.

This is one of our favorite campsites that we've visited several times.



It's 100 yards off a maintained BLM road... I'm not sure we could get to it if we didn't have the clearance we do.

Yes, like that! My guess is we see similar terrain. Lots of spots just off the highway or down that 2 track a few miles. Lots of BLM land. We drove hundreds of miles of roads through it last year from our base camps. I am willing to be inconvenienced by a bit higher ground clearance of my build rather than not being able to leave the pavement but want the classic Benroy look.

Hmm, Just what would happen if a sealed AGM battery took a bath? I'd be shocked if its all that serious.

And since I did put mine behind the axle, someday I may be...

It should be fine. It’s a rock or stump that I was concerned about.
