Yes, you are on the right track. You would essentially be setting up 2 separate 2 tank systems. So using (2) of the MB Sturgis High Capacity Two-Stage Auto Changeover Regulator # 888001-MBS will work great for that. You would then also want (4) of the MB Sturgis Propane Pigtail # 100575-15-MBS to connect your tanks to the regulators. Then you can either get (1) of the MB Sturgis Propane Hose Assembly # 100383-60-MBS if you want to disconnect from the regulator to switch over to the second... view full answer...
I do have some information for you that should help but unfortunately we have not yet had the chance to install the Global Link RV Entry Door Locking Latch Kit part # 295-000021 on a blank door so we do not have an install video. It's a pretty simple install that I think you'd be able to handle pretty easily. Basically, you will want to mark a cutout about 2-1/2" wide x 3-1/2" tall in the face of the door near the edge where you want the handle to be and then use something like a dremel... view full answer...
