I hesitate to post. If I knew the potential purchaser I would have sent her a private email to avoid the hassle of this forum. Here goes...
To the person wanting to buy the Boler
17 and planning to tow it with a Honda CRV.
I know nothing about Boler
17s as to their weight
and frontal area though it appears that a loaded Boler 17 can weigh about the same as a my Scamp
16. I believe a Honda CRV can easily and safely tow 2500 to 2600 pounds.
We all seem to worry about weight
but to me a big concern is the frontal area. As the frontal area, height times width, gets larger it puts a bigger strain on the tow vehicle, particularly at high speeds.
A way to consider frontal area is imagine towing as sail perpendicular to the direction of travel that is 10 x 10 feet, not dissimilar from the parachutes used to stop the space shuttle. Wind resistance is a big deal. (Please remember I know nothing about a Boler 17's frontal area; I have never even seen one.)
As a reference point, my 2004 Honda CRV has functioned beautifully towing a 1991 Scamp
16 and even a heavier 1995 Casita
16. My experience is that you will not find a more reliable small vehicle.
Wishing you well in your search for a trailer,
