Yes we are...
Haha...Yeah, in a way we are approching the same problem from opposite directions. From my understanding the containers don't like a lot of twist/flex. They, like any steel object will deflect and rack out of true. Since they were not designed to be used as a trailer it kinda complicates matters.
I think that is why the military dolly sets only handle a 20 footer...though I know the only real difference is the extra length, I think they use some sort of spreader bar/rails...to goin the two halves together?? Maybe? Not quite sure.
Though I suppose if the unit had a small enough tongue weight, rolled well, and the container were empty, even a good diesel pickup may be able to pull it?? Guess there are a lot of variables to think about. Distance, road conditions, road construction, accessability...?
The fact that you won't be "doing it everyday" is true. Which is where I have to make myself think and refrain. Being thrifty (ok, cheap!) can be a double edged sword. I gotta balance the cost saved in paying others to transport it X number of times, distance and access too. Some drivers won't touch dirt. But then if I could actually FIND one of these dolly things...how hard are they to come by? What all is involved? Would my truck even pull it?
I am trying to force myself into understanding that 20 footers are better/easier to work with. But already owning the 2 40s...gotta think on that one. I am curious what would be involved with transporting them via rail car? Since all the good "deals" are ones in costal regions, how expensive would it be to have one sent via the train? I'm shooting for Colorado and that is a long drive from the gulf even with an empty one. Can't be cheap on gas/time. But if it was much less to have it delivered to a rail center...I could use the dollies to drag it off to some property...? hmm... Any train people around here?
