Installing second gray water tank

I'd like to install a second gray water tank under my TT. There is room for it forward of the other gray tank and I plan to connect the two of them at the bottom so they both drain at once.

What sort of venting will be required? Does anyone have a recommendation for a shop in Southern California that does this sort of work?

Thanks!

If you’re looking to have the work done, these guys are the best in So Cal. Located in Chino

Rather than adding plumbing, why not just replace the existing tank with something bigger?

Make sure that you dump your tanks before leaving the campground. You have added a great deal of weight (capacity) and you don't want to go over the safe weight ratings for your tow vehicle.

It needs a vent and it has to be large enough to allow quick draining. Seems like the best thing to do is connect the new tanks vent into the old tanks vent at a location above the old tank.
