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
Depending on how close to the minimum performance edge your RV battery setup is. It's important to remember that a diode has a .7v loss. Loss makes heat, that is why this type of isolator has fins.
Isolator's
Ultra smart ... Redodo
Smart...Cole- Hersee 48525
Standard ... Cole-Hersee 24590-8
Cole-Hersee uses silver contacts not copper.
Big battery, small alternator, to protect alternator a DC to DC charger....Victron Orion TR 12/12- 18A
There other Dc to DC converters
Thats not an isolator, it is an auto reset circuit breaker. it is toast, so your real isolator is not working. MOST RV of this vintage the isolator looks sorta like a 35mm film
can.

If you understand the program for the Redodo its perfect
There are 3 and 4 post isolators. Both have the 2 large terminals. Large terminals hookup is... output wire from alternator to 1 terminal. To the same terminal large wire to truck battery. The other large terminals is to charge the house battery, from that terminal a short wire should go to the circuit breaker C/ and then to the house battery.
Broken C/B house battery no charge.
3 post isolator, 2 big terminals, 1 ignition on wire. The case is the ground.
4 post isolator, same as 3 post. BUT the case is isolated and the 4th terminal is the ground.
A Volt meter the the most important tool for you to have.
