Best approach for more LP into our RV...?

Hi Bobbo and yes, it is CO......Actually the whole shed is vented as the corrugate metal panels bolt into round vertical poles and there are gaps everywhere.

Oddly, the CO detector inside the RV is at eye level. I do have a battery powered CO detector that is more sensitive to CO levels and the directions say to keep it about 3 feet off the ground.

Thanks for your post
