Another Elec Problem, Need for Schematic
No sooner had I said I, personally, hadn't has any wiring problems than I had one ... a serious problem that I did manage to fix after a couple of hours of needlessly taking much of the underbelly off. Had I had a true electrical schematic/blueprint of the unit, I could have fixed it in 10 minutes, with a ton less anxiety. Read on, y'all, just in case you encounter the same.

The Problem:
Suddenly I lost 1/2 of my circuits. The furnace, water heater, Dryer/Washer line (powering our extra freezer!) was dead. "Suddenly", I say, because we had hot water about 12 hours earlier, but now we didn't and our food was well into thawing.

First action: Check and recheck and reset ALL my breakers. No help.

First suspicion: the park's power supply (50 amp). We'd had one leg of the park (another park, a 30 amp supply) trip its breaker on us a month ago with very similar results - 1/2 our circuits gone (different half, like the TV & outlets in the larger slide, etc.) Checking it out with a volt-meter, saw that was NOT the problem. Full power at the plug, and out of the end of my shore cord.

Second suspicion: The receptacle for my cord was at fault (like a connection from the inside came loose). Pulled it out, checked all the connections, it was fine.

Third suspicion: I'd read before where wiring broke inside from abrasion or stress of the slides. So we (my son-in-law had come to help) began opening up the under belly to inspect the power cord (it's the same sort inside the house as your shore cord but without the heavy rubber insulation). Saw nothing. Began to wonder why only one line (the red supply wire was live at beginning end, dead at the main breaker) was out, and why no sparks, tripped breakers, etc.

Fourth suspicion: There must be a junction box somewhere under there where one leg (our red wire) had rattled loose. We started opening more underbelly, concentrating near the furnace (only place it seemed likely a j-box would be needed). We did find that we suddenly had two power cords... one going north (toward front), another right beside it coming south and turning west toward the breaker panel. But NO J-box in (our limited) sight.

Bright Idea: Before continuing our disassembly of our unit, go up front to the Gen-prep compartment and the battery compartment. Look for some sort of j-box, or connection place for the generator cut-in. Lo & behold, behind our batteries (had to take one out to get to this) was a large metal box with two power cords going in/out of it. Opened it up, a connector bar with one line (all 3 legs of the cord) connected in, and the same for the other going out. Plugged in our shore cord, saw a spark from the red line. Checked our breakers... we had power.

The Problem/solution: The one red lead had not been inserted enough, nor the lug screw tightened down enough (that proved true on 5 of the 6 connections!) EASILY FIXED.

THE COMPLAINT: Had I had a wiring plan, I would not have torn apart the underbelly, and probably checked that junction box even before suspecting a damage power cord inside. My 2 plus hour job could have been 10 minutes, and I would not have needed to open up (and unsealing) the underbelly, insulating foil, or metal wrap-around flashing, etc.

PLEASE Keystone A useful, model specific blueprint could be prepared by copying your own already-existing plans, and run off on the copy machine with a cost of mere pennies... DO IT! And do the plumbing too. And make it available to all of us, not just future owners!
