The last totaled burn-out I did for Good Sam, allowed me to see the quality of the then brand new Alpenlite trailer.
The burnout was caused by a defective neutral.
Seven hot wires 120vac had been punctured by staples. Some of the longer 12vdc wires had been extended using plastic butt connectors. The tank's info panel had a dozen wire nuts.
I had a helper who was saving up to return to Mexico City. The guy had a near-genius understanding of cabinets and paneling from several years working at the Fleetwood factory in Pomona. One wire powering the outside porch light had been stretched so tight it had been pulled out of a spade terminal.
The owner kicked in the difference and he opted for a Trace 2500SB inverter. We upgraded the batteries to genuine Trojan T-105's. Homero (?) readjusted the furniture to allow a couple of inches more clearance for the dining table. Sal, at Kool Fun, sold a then hard to get refrigerator control board and hot water heater control to me.
The biggest pain was running a 24 conductor wire from the water tanks to the monitor panel.
Armando my hyper supercharged assistant did far better work about twice as fast as the Fleetwood crew according to the discharged Fleetwood employee (whose verified name is lost to me).
The owner opted to replace the Onan Emerald governor with an electronic governor (which did not get affected. At the time the price of the Woodward unit was less than half the price as it is today. During testing, he could scarcely believe 60.0 Hz versus Onan's sloppiness and tendency to surge. I cold not flatten it out.
Good Sam did not pay for the upgrades...the owner did. The owner brought the rig up from the San Fernando Valley and helped strip out the burned harness. The loss of neutral had occurred at the hot water heater after burning through a connector at the entry drop.
I got too good of a look at how OEM wiring was installed. Yucko, The new guy had pronounced it as "typical".
The insulation of the Alpenlite impressed me. Those days were in the summer. I placed a swamp cooler at one door and the air exited out the other end. The ex-factory worker looked at me like I was nuts when I asked him how the factory did it,
