Did I make a mistake in Financing? How long do you finance?

I've only skimmed through all these posts, so perhaps someone else has mentioned this. To the OP, you may want to consider that for a large part of the time of this loan, you will likely be upside down, so think about the insurance situation should you be unfortunate enough to have a major loss on this trailer ( accident, theft, fire, tree falls on it, etc ).
