Poly scratches easily.
Useful additions for anti scratch. https://xshield-protect.com works with glass and poly.
Also check out window security film, I don't know how it would work on the outside.
The have been reports of the front overhead window, on some campers, shattering for unknown reasons. These films would help keep all the bits of glass out of the overhead bed.
A few drops of oil on the blower shaft will work for a bit.
The bearings are what is called an oilite bushing, it needs to be soaked in oil. Most also have a felt fuzzy to retain the oil longer.
Decide on your skill level and what your time is worth.
When time permits....When I redid my front cab, I did what you did, plus a bit more.
I installed a layer of Reflectix under the carpet and a extra layer over the transmission to help with heat.
To help with the looking out of pill box gun port effect, I raised the drivers seat 1".
The Reflectix worked well in both cases.
There are better products (dynamat), that the the auto sound guys use. It is more $$$ than Reflectix.
I got booted and when I tried to rejoin I got one of those captive things to prove I human. "155+6=" so I answered 161. Captiva said wrong answer.
About 5 days later I was back in with no action on my part, poof magic.
LOL my Grandfather was a finished cabinet maker in his day. No nails or screws. Hand cut dove tails and dowels.
I inherited a 6 rack gun cabinet that he built around the 1900s, the only metal in it is the two door hinges
As I'm updating my RV I discovered that particular gene skipped my generation.
Your stuff looks great.
Did the same thing, its the easiest way. But you have to get 6 bolt rims at the same time. If my memory serves me correctly the 1992 brake rotor is 10mm larger in dia.
I THINK that I remember some of the big steps on this swap.
The biggest thing was torsion bar front springs vs coil springs. Oldest (4 eyed) trucks has coils and this is not good for the swap.
Not really useful for an RV, but looks interesting for a playhouse in your back yard.

During my formative coffee drinking years, I lived in Hawaii on different islands. So I'm sorta a Kona guy, although Kauai has started growing/roasting some boutique flavors that are interesting.
