I'll dive in again this weekend and investigate more, check ducts, etc. I did check the ducts when I installed the new furnace Winnebago sent to me after the warrantee expired. The furnace the dealer had worked on was dented, with broken tabs, smashed logic board and mounts, and all the fins were broken off the fan. I was pretty shocked when I saw it.
The dealer said there isn't a HP, but I think they're wrong. I'll confirm either way first thing.
Replacing the LP regulator is likely next on the list. Is there any brand or style regulator that's better than the others? I'm seeing mostly no-name products out there. Might as well get a pressure gauge, too.

Exactly. That's the best place to start. Also likely why I think it's a fuel issue with the pressure or regulator. I went right to the more complex problems after I saw all the damage to the furnace caused by the dealer.
Oh Dear! Were it me.... I'd take photos of every thing you find on that junk that was installed. There's just no excuse for that. Also, grab your receipts and documents. Make copies (lots of copies). Then go to work (politely) with the guys who installed that.
OK... regulators. What I know. The OEM on a '16 View (and I suspect other MYs) is made by Fairview. Folks 'say' that the Fairview is low cost (true) item that has some design issues (probably true). The Fairview crimps the diaphragm between the halves. Look at a photo on the internet. Allegedly, this starts stress cracks in the diaphragm that eventually propagate and cause failures. The preferred one is made by Marshall-Excelsior and uses a different construction/design. A little more $$$$.
I've replaced two Fairviews on our View. I don't think it was due to a design issue with the regulator. Certain MY Views had a recall on LP hoses (wrong material used (no doubt CHEAPer) and it reacted with the LP causing failure. A consequence was that the debris/gunk/slime/crap FODDED the regulator and it failed. WBGO recalled & replaced the hoses. After the recall, the regulator failed in about an hour's use ..... because there was crap left in the lines that were not replaced....... DUH!!!! So far... after quite a few hours of use, it works fine.
(IRRC, the Fairview (different name 12 years ago was installed on our TT. It worked fine for 8 years. So... I'm thinking the design is acceptable and the premature failures were due to the facocktah hoses installed by WBGO and not by an issue with the regulator per. se. )
