A/C on solar is a no-go, no matter how many batteries you install. Maybe if Musk gets involved.

I think their 'Shortie' 19-footer is actually a hair over 20' (see above). I believe their V6 models are actually 20'-7".

I assume you've got a maximum length requirement of 20'-0". That's going to limit you somewhat.

Presumably, somewhere in the local 'Law', it's written "... no RVs over 20'..."

Both Dolphin and Winnebago used green wires to the tail & side marker lights. Perhaps there is an RVIA 'standard', though I never found one when I looked. The license plate light (as seen in the Winnebago drawing) is (logically) on the same circuit, also using a green wire. I can only guess that the 'red and white' wires originally referenced are the wire colours on the license plate light. If so, connect the red (+) wire to the green (+) wire and then find a ground somewhere. Dolphin used white for the ground (-). My 'theory' can either be tested by wiring it that way and perhaps blowing a fuse or by using a multimeter.

Take the bumpers off and measure again!

I don't have solar, but 200w sounds like more than enough to me. I think your biggest energy hog would be the furnace blower. Perhaps time to find a younger 'RV guy'.

"Approximately 21'." What's their limit? 1991 Conquest Toyota Micro Gulf Stream.pdf

The problem with that theory is that the motorhome manufacturers had to extend the OEM Toyota wiring to reach the extended 'house'. Wiring colours was a free for all. This is an example of Winnebago's version:- Yes, a multimeter and operator is essential.

Looks like you're almost finished.

Other that the Dolphin wiring diagrams I posted above, I've never found any others. Sorry. Your best bet is to find someone with a multimeter and a basic understanding of 12v electrics. Fortunately, the circuits are simple.

Beer and pizza works too, at least with me!

If you have a '2-way' fridge it works on propane or 110v. To operate on 110v you have to be plugged in. The '3-way' option adds 12v DC as a power source.

Make and model of the fridge might help someone with the same one answer more specifically. I'll guess first. Dometic RM2401 or RM2410.

And don't overtighten the pan bolts. They just have to be tight enough for it not to leak, not hold then engine together. I'm sure there's a torque spec somewhere.

The simplest solution would be to buy speedo adapter. About $100. This is an invoice from 2014. They could probably work with GPS MPH vs Speedo MPH readings. Side Note: It's amusing that the 'Specialists' can mis-spell 'AXLE'!

That sounds about right. When your leak is fixed, go back and wiggle/tug the wires and see if you can get the pump to stop again. That should lead you to your problem. BTW, I just moved your 'Leaking Toilet' Thread out of 'Electrical'.

My 'Bill' is in the mail. Did I mention that I hate electrics?

Unless you're in the mood to buy a new pump for maybe nothing, put 12v directly to the red and black wires on the pump and see if it works. You say you're getting no power to the pump, so I'd suspect the Monitor Panel switch.

I've read this before but can't really find any evidence.

This is your 'Monitor Panel'. 4 screws hold it in place. I assume that activating the switch makes the light go on and off? It's possible that the switch is in the 'Power' or 'Ground' side.

This is a drawing of your pump. You'll see that ShurFlo uses the more 'conventional' wire color code of 'Red = power (+)' and 'Black = Ground (-)'.

Your 'Converter/Control Center' is divided into 2 sections. The left side is for 110v AC only for when you're plugged in. I've no idea why the label a '15A fuse', because those are actually 'Circuit Breakers'. The breakers protect the 110v wiring to the outlets, air conditioner and fridge when on 110v. The right side is for everything 12v DC. Lights, water pump, etc. Without drinking a lot of coffee yet, I'm going to GUESS. - For your pump, a (yellow?) power (+) wire goes from one of the fuses in the converter to the switch in your 'Monitor Panel and then a (yellow?) wire to the pump. - To complete the circuit. a white ground (-) wire is used.

It is a 5-lug axle.
