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.
AeroPress works good on the road
Bigger wire size (6ga) from isolator to truck. Effectively your charging 2 batteries at the same time through this wire. 8 ga from truck battery to DC to DC and 8ga to house battery. I have a longer run so everything is 1 ga larger. 15 ft from alternator to coach battery I'm using a 12/12/18, works good
The absolute most important in your RV tool box is a cheap digital volt meter. With an RV this old you have NO ideas what the previous owner "rewired" to make it better. my Toy would go a couple of months of Wyoming winter and crank just fine.
A $10 Harbor Freight Volt meter will let you look for phantom loads and other useful things
P.S. There are several 12v RV repair guide books on the net.
P.P.S. Something like this works wonders...https://www.amazon.com/ECO-WORTHY-Maintainer-Waterproof-Adjustable-Controller/dp/B0F53FW516/ref=sr_1_1_sspa?crid=1HN3H0AY4R0C7&dib=eyJ2IjoiMSJ9.ShbFcjaWzWENMQYuICBMOiDa8A6IJfpT9oTE-Rfrqp-zSALKhaEfs7neXc2sZ_emOzjoP7jAB4IEt5wmC1gGBhtcqKrKVvuhIZYco07o4859dQa06GnoHvBVl8smVTIi8JxiIHBBbDBv_KMu-Mbu0mXUF2-gb8zlfWSLxz_jcRmA0sDxTSWVAGhTnYK0hkdfSpz52fTHdwhGEI0QtCOfEEfRPi6PGRJfXe0tEO9uvuE.iANZpOIsDC-0a0qHPdeEuOoLnX5YQ6emRG8H9PpS0y4&dib_tag=se&keywords=eco%2Bworthy%2Bsolar%2Bpanel%2Bkit&qid=1777087994&sbo=9ZOMT9Jm0JH%2Ft%2BWi68iDSA%3D%3D&sprefix=%2Caps%2C337&sr=8-1-spons&sp_csd=d2lkZ2V0TmFtZT1zcF9hdGY&th=1
What is your travel itinerary? We've stayed at wonderful private family run camp grounds and horrible state camp grounds.
When we traveled in our toy the schedule was Walmart x2 and then a camp ground.
Charge batteries off camp ground shore power (pre solar), now days not a problem, Dump holding tanks, every other camp ground do laundry
E-bay. 10,000 choices. 99.9% are made in China.
Choice of flush mount, ceiling mount (replacement for OEM) , under cabinet swivel mount. Many ceiling lights have a adjustable color temp.
Just in case choose those that use common LED replacement bulbs, although most use surface mount clusters that aren't replaceable.
I dunno about this, my Escaper rode much better on Poly vs worn factory bushings. New poly vs new stock who knows.
The poly bushings make the springs work properly instead of wallowing around. BIG question is what brand are your shocks and how good are they?
I thought the heater blower fan used oilite bearings.
Last time I "fixed" a heater blower I removed the motor and opened it up and carefully hung it with the bearing submerged in -0w20 oil for a day then did the other end. Just have to be very careful to keep the brushes out of the oil.
Up grade, simple😏 change rear axle ratio to 4.88. The 3.0L 3VZ v-6 Exhaust crossover delete kit works wonders
The Lexus 1UZ-FE V-8 has been swamped many times
