Battery Box Vent

Interested to hear how you are venting your battery box if your not using the OEM location for like a solar install.

Switch to AGM batteries and there's no need for venting.

Sorry, not going to AGM. Have fairly new Crown wet cell and planning to add two more. So if you have any recommendations to my question I would be glad to read them.

No need to apologize, what you choose is entirely up to you, BUT it would have been germane to the discussion if you had mentioned this in your first post. You may consider your Crown flooded batteries to be a force du jour but there's no way I'd be locating any flooded battery so close to an inverter, enclosed in a vent box or not, certainly not now when batteries that require no venting are so readily available. I had a similar situation in my own trailer so when I replaced the aging tongue mounted flooded battery I chose an AGM and mounted it in the front pass through cargo compartment so the cable runs to the inverter would be no more than 18". No vent box required, no concern over having the battery mounted so close to the inverter, no need for maintaining fluid levels, minimal voltage drop under heavy inverter load. Even so-called "premium" batteries like your flooded Crowns are old technology that are now easily replaced with better products like AGM and eventually lithium once the price becomes more reasonable.
