Depends.....Local U-hauls will weld one on. They might even be able to
fit you up with some sort of rental thing that you return when done
with. In the "olden" days it was quite common to drag the family sedan
to the local rental yard and have them outfit the family car with a
temporary trailer hook-up for a move across town or across the nation.

But, I haven't done that in 30 years or so.....But I imagine it is
still possible and saves you the expense of buying a hitch.

Otherwise, yellow pages under trailer hitch..... Don't imagine the
Camry has predrilled holes for a hitch....
