Yesterday, I saw for the first time, a two horse in-line trailer.  Looked like a GN too.

It was in a pasture by the road so I didn't get a good detailed look.

Questions:  what was the reasoning for a long narrow trailer?  Did the first horse have to back the entire length to unload?

Maybe it's time to go back to this design, the inline bumper pull. It worked well during the gas crunches of the 70's as you could pull easily with anything that had enough power to pull - cars ,half-tons, etc. as there was minimal weight on the trailer hitch.  No Peterbilt's, 450's, or 550's required. And they pulled like a dream- even at 80mph when the speed limit was still 55. But a real B____ to back up.

When I was a kid in the 60's there were a few two horse shotgun trailers in our part of the world (New Mexico).  My dad pulled one some. It was pretty common then to pull two horse trailers with a passenger car- a shotgun trailer pulls like wagon. It doesn't put any tongue weight on the tow vehicle. They were pretty stable as long as your tow vehicle was heavier than your loaded trailer.

You know, I think about some of the things we hauled horses around in those days- we (and our horses) are pretty fortunate these days!

I had a Miley GN 2H inline back in the late 70's when I was running the rodeo circuit. It had a very tiny weekender in the front. We woke up one morning, heard the laughter and then saw a sticker that one of the clowns had put on it. It read............................

 ONE WIDE TWO DEEP!

We put alot of miles on that trailer, used it hard for several years and sold it for more than I paid for it. It pulled GREAT! Back then you saw a ton of them mostly bumper pulls since the bigger LQ trailers had not really caught on and the slide in campers were widely used. The front wheels on the inline bumper pulls made it real stable for tying horses to even when it was not hooked to the truck.

Some of tlhe  advantages of a two-horse bumper pull in-line trailer were back in the 1960s and 1970s, you could have an in-line trailer custom built to be 40 inches wide and 7 feet tall,  remember this was in the day when most trailers were small 2 horse side by side bumper pulls and goosenecks still were in their infancy.....  I used to haul a stallion in the front and a mare in the back..... the front axle was on a swivel plate and the hitch had a shock absorber in it so when you slowe down the shock would absorb the energy as you put on your brakes,  it pulled like a dream but you did have to know how to back them..... I had three and quit using the last one in the early 90's.....had a tornado hit our place the stock trailer and 2 horse goose neck were on their sides,  the in-line was still upright!!!!! 

This one's nice!!  http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&ih=011&sspagename=STRK%3AMEWA%3APIC&viewitem=&item=320211439028&rd=1

I forgot about backing them up.......you are right, it was interesting to say the least!

Yeah, but pulling them was sooo easy!

We never had that issue with ours. We had one in the 70's that pulled behind a Dodge Charger and a Challenger. It was a '70 or '71 model Gruenwald. They were common place at the shows in TX, OK, KS, CO, NM. I can remember 4 horse versions of it also, just not very many.
