I ran an extension cord the length of my tt and since my trucks had both a 7 pin and a 4 flat plugin i used 2 plugs.

This is what I did with my last trailer. My current 5er allowed easy access to the wiring at the rear, so I pulled it from there. I also picked up some resistors with heat sinks to reduce the brake voltage to the second trailer's brakes as the 5er has much more weight on it and have 12" brakes on all axles.

carringb,
That makes sense! Good plan, thanks!

My concern now is wiring a 4-flat into the trailer's brake lights. I haven't dug into it yet, but I can't find access to the wiring harness. It's behind the wall somewhere.

All the TTs, for the most part, run the 7-way umbilical to a junction box in the from of the trailer. My last two trailers had it in the front compartment, but my current trailer has it mounted underneath in its own electrical hatch. The is by far the easiest spot to tap in to, and will reduce the chances of overloading the trailer's lights. It would require a full new run of wires from the front to the rear, but a recycled extension cord could serve that purpose, since you can just ground directly to the chassis at the rear.

Getting back to the OP's topic...

I am also planning on double-towing this year. My Jayco has the full I-beam frame and I found a hitch application that just might work!

The Curt #12923 is a frame-mounted receiver hitch that is adjustable to several widths. It has a 3500/350 capacity that will work in my circumstance. My second tow is a small Shorelander single jetski trailer that weighs about 1200# with the ski on it, so not much there.

Legal issues aside (you seem to have them covered), the only thing would concerned with is weather trailer brakes are required on the second trailer, and weight balance of the first.
You are going to want to practice towing doubles before heading to the mountains.

I'm not saying that your law enforcement friend didn't give you good info, but I would suggest that you contact someone that deals with commercial vehicle rules for your state. Commercial Vehicle Officers (CVO's) have specialized training and hands on experience with towing and towing requirements.

They have CVO's in most states because the rules are complex and difficult to decipher just by reading the statutes.

Also, there are no reciprocity agreements between states regarding towing as far as I know. That means that just because you're legal in your home state, you might not be legal in another state.

Someone that can double tow in Montana, can't double tow in Washington.

I really doubt that the OP (who lives in Wyoming) has any intention of taking his double tow to Washington State.
In fact, the OP stated:
"I will not be pulling double further than about 100 miles and yes its legal in my state of Wyoming. This is mostly for hunting so a trip up the mountain is about as far as I will be going."
Seems to me that pretty firmly establishes the limits of his intentions.
As for me (I live in Montana), I have no intent to double tow. But then, I have no intent to go to Washington anyway, so it doesn't matter what Washington will or will not allow.
Reciprocity Agreements usually only cover driver licensing, insurance requirements, and registration. It is interesting to note, though, that even though my ATV is street legal in Montana, that does not mean that any other state will allow me to ride it on the public roadways!
Recreational vehicles are quite often exempt from Commercial Rules.
