Frank: sorry to see the photos of Anna. Bummer. Hope you are able to keep it original.
This was the first time I saw this thread. FWIW, on my trailer I run a marine style Blue Sea terminal fuse
on the battery post. That way I have no "unfused" lines running into my trailer. The fuses are not cheap, but they are fully enclosed etc. IIRC they have a 10,000 amp interrupt rating.
I have recently purchased an AM solar setup, although they have an upgrade to a high quality circuit breaker (I think it's one of these
Note pdf file) I got the standard fuse holder. I am going to order that circuit breaker today. BTW it has a 5000 amp (at 12V) interrupt rating. Pretty stout and worth the bucks. I think I am also going to look under the couch to see if anything else needs an upgrade fuse/breaker wise.
This stuff kind of makes me wonder why AS doesn't make more two door models. Many moderate and larger style SOBs (even cheapo models) have two doors. A huge safety feature in my book. Seems like it should be some sort of code requirement. A lot of folks would have a hard time getting out the window. This was something I use to think about when we contemplate getting a 5th wheel years ago, how do you get out and on to the ground safely from the bedroom in one of those. Especially when you think a lot of folks that own them are older and lets face it, look around the campground, out of shape.
If there is a fire, getting everyone out safely is the #1 priority. The trailer is replaceable.
