Also, I will be towing two jet-skis.

I'm not sure that you can modify a CRV to become a heavy duty towing
vehicle.  That would be a truck.  But I can give you some advice to
tow with what you have already...

Drive slowly and carefully.  One reason for the tow capacity is
safety.  The vehicle braking, cornering, and general handling are
affected by towed weight.

Also, keep the engine in a decent RPM range.  Do not "lug" the
engine... stay out of low RPM range under load.  This means
downshifting if it's a manual transmission, staying OUT of overdrive
if it is automatic.  Don't redline either, obviously.

Lastly, when going over bumps, do in gently.  The frame could be
damaged if a heavy load slams the trailer hitch from a jarring bump.
