length with trailer?

[manitou]

I'm working with a rather compact size parking spot (unless I pay to park it in a lot nearby.. but I'm trying to be cheap (responsible..ugg) with my toys for now).
I've got just about 20' and that's pushing it. I can stick out about a foot more then that with the trailer tounge... and with the fold back tounge.. maybe a V18 (I didn't know there was such a beast) would work. I've limited myself to 17's with baitwells on either side of the OB, or 18's.

Suggests on other make/models is appreciated as well.

thanks
