Peg, at the top of the opening page there is a "search" heading. Click on that, type in "buying checklist". gerogiegal asks the same question, click on gerogiegal and there is a check list!
Also, what you have stated, a 2007 used 1701 Hi Lo is a bit misleading, 1701 is a 17 foot unit made in 2001. If it were an '07 17 footer it would read 1707. So, as you can see, the first two digits are the length and the last two digits are the year.
Best of luck in your search,
