In-vehicle private car

It is a question in the thing of an in-vehicle private car (積車).
although exchange is under examination now -- a squilla -- carrying the car of a tongue,
The fellow who becomes a full flat, and the fellow who becomes an angle of 5 times
I think that I will make it either. Which is good?

Although the car where the full flat is lower is likely to be put if it thinks ordinarily,
It is said that the car where the fellows from whom an acquaintance becomes a reason and 5 times are low can be put.
If it can do, I do not want to use a board, a slope, etc.
Supposing it does not care about a price, which is good?
an old experience -- a squilla -- the way with an angle says loading of a tongue vehicle -- it is .
a squilla -- it becomes unexpected at the time of loading of a tongue vehicle to become a problem into the portion of a "belly" rather than an order overhang.
If it is with an angle, and even a front wheel appears, after that, it will appear satisfactorily (almost), but after a front wheel goes up in case of a full flat, the portion of a "belly" may be caught and it may be in an "it is one difficulty as 1 難去 again" state.
what is called -- "all over" -- a squilla -- in the case of a tongue, it is this pattern rightly.
If it does so, for what purpose is there any full flat?
