At Uhaul, look at AV series trailers. They are covered and lighter. U can haul a pin on its legs, or stand it upright. Its a 5x8 trailer...very economical.

In my enclosed trailer I have E Tracks down the sides and I use heavy duty straps to secure the games to the sides. The sit where put, and always arrive safe.

I have a 6X12 enclosed trailer with E-track I ordered installed when I ordered the trailer and I have a ramp door. I have them wrapped and strap them down securely ...I take my pins to shows in it all the time, and no issues. If you rent that particular trailer, you also have to worry about weather issues that you don't have to worry about with an enclosed trailer... I would not suggest transporting pins with legs on ever (but that is just me) I also generally do a check of connectors and such when I arrive and unload/set up the pins at the show to insure that anything that might have worked its way loose gets re seated to not cause any issues. These are electronic devices and things do happen, but with a certain amount of caution and "common sense" (not sure that is the correct phrase but if you wrap it strap it and check things out) when you set it back up then you should be good to go!

If you have room to store it, a 6x12 enclosed trailer with a ramp door is awesome for transporting all kinds of stuff.

U-haul trailers are the only way I've ever transported my pins since none of my cars have ever been pin-friendly. But they've all had hitches installed. I use their enclosed trailers for one-way and longer distances but 95% of the time I use their standard 5x8 AV open trailer.

I have a stack of packing blankets and ratchet straps to safely secure the game at the front end of the trailer. If I don't mummify the game in packing blankets and shrink wrap before I load it on the trailer, I'll put a packing blanket under the machine to help slide it onto the trailer and so the underside doesn't get all scuffed up. I'll the use plenty of blankets between the game and the trailer sides and underneath any of the strapping if necessary.

Just make sure the game is properly secured toward the front of the trailer so it won't budge and you should have no problem. They don't bounce around as much as you might think, if at all. Those trailers are actually very stable with a 250+ pound machine strapped in them.

Transport in an open trailer is fine as long as you wrap up the body of the game. to keep the weather off.
I would not recommend it for a long distance during winter. and I highly suggest putting the backglass inside the vehicle.

We used to transport games all the time in an enclosed utility trailer.

Legs on or off, nothing ever happened to the games. They are tough.

Most rental yards have trailers cheaper than Uhaul does (at least in the States).

How many williams DMDs would fit in a 6x12 enclosed trailer?

I have a couple single mattresses the kids use for sleep overs etc, and I lay one down in a small enclosed uhaul. Then strap and put packing blankets around the sides. They sleep like a baby!

As long as it's wrapped correctly, you will be fine. Use moving blankets, tarps and shrink wrap. You will need able to drive through rainstorm fine. Also if strapped against side, legs off, you should have no issues. Just inspect connectors upon arrival and you should be fine. Go for it.

U-Haul open trailer or enclosed are about the same price ,so why take a chance with the weather?

I can fit 8 in my 6X12...I have a side door on mine, so fitting 8 is a bit tight with 1 overlapping the side door a bit.

I assume then you have a tandem axel trailer Phoebe?

Nope it is a single (Dexter) axle. Looked at the double axles, but did some research and decided that for the extra expense and what I wanted it for, the single Dexter axle was just as good ride wise (IMO). I haven't had any issues with it and I've had it since 2009.
