David,
Yes, Rental companies prohibit towing and also limit crossing some
state lines, but many people still do it......yearly....for soaring
vacations. The trick is to request a vehicle that is sold 100% with a
hitch receiver as standard, like a Chevy Trailblazer. Then purchase
the wire adapter, $15 at any parts store. Rental is $500 extra if you
drive it one-way only. Calculate cost with gas and hotels and compare
to options 2 and 3 below:
Option two is to post here asking for someone to deliver it for you
for a fair price, or even part way to get close enough for you to meet
them.
Option three is to use a shipping auction site like uship.com to list
your request. There are post on RAS about this already.
I evaluated the cost of all three options, tried option 3, then got
lucky that Option 2 worked out.
