What type of trailer are you planning on towing wiht your XC70?
How much does the trailer and its load weigh?
I went to U-Haul and got a Class II hitch (300# tongue load and 3,500#
gross weight) with a 1.25" receiver. It is great. It is U-Haul model
36297 and costs $115. It only took U-Haul 30 minutes to install so it
was a good fit. It is black and the receiver is under the bumper and
forward so it isn't very noticeable.
The U-Haul receiver is $19.95 and curves up so that it is positioned
behind the bumper.
For wiring, I got a wiring kit from a trailer shop near by for $20. The
kit has the black box that converts the brakes plus 2 signals to 2
signals so that it will be compatible with the standard 4 pin plugs. I
wired it into the plug next to the spare tire. It doesn't blow anything
out. The bulb out lamp works just fine. Then I ran it through a passage
to the lower right tail light access door. It is completely out of
site. When I need it, I just open the door and run it out under the
tailgate door through the rubber gasket. The advantage of the kit is
that it has black shrouds that cover the wires and a cap that snaps over
he end that plugs into the trailer when it isn't being used.
