I'm installing an inverter in a 2022 Keystone Passport 268BH. Has the prepped inverter loop.
First, is the inverter selection. I'm considering a Renogy.

I'm on a budget. DIY. I'll keep the WFCO for shore power charging. This inverter has the UPS. So I don't need to install a seperate transfer switch.
Any recommendations for other products in this price range? I've read concerns Renogy inverter always having to be on. Even when on shore power.

Second, I'm trying to figure out the DIY. In a Passport breaker board, is there a switch for inverters? Photos attached.
Third, I just bought a Litime lithium battery. Hooked up on the external battery rack on the tongue. I'm worried about theft. I don't want to have buy an expensive battery shackle if is it not necessary. I want a 2nd battery in the future. How do you get the external battery cables into the storage? Also, seems this would make installing the inverter so much easier. Connecting the battery cable would be easy.
Otherwise, have to cut a hole through the storage to the tongue, to run the connection from inverter to the battery that is on the external battery rack on the tongue. Should I be worried about this? How? And, what do I do with the 2nd battery? There doesn't seem to be room on the tongue for two batteries, and theft/security is a concern.
Thanks for the help!

Inverter wired to Giggy Box
Has anyone wired an inverter directly to the Giggy Box vs direct to the battery? Obviously would install an inline fuse in the positive cable.
