Thank you for all of your thoughts, John. I was planning on installing my own box that is a bit smaller than the OEM version. I understand now that it is just the box that is the limiting factor with tongue lengthening. I also like how you use that overflow space on your trailer, I am thinking of something similar that would add utility and reduce would be cost of shorting this trailer. Other than these concerns/considerations, I think the Karavan is a very worthy consideration given you can get it built from HD for $850 on sale and has 12″ tires on it.
