As someone who's been cross country,NY-CA-NY ,I would agree with buying something used then sell it when you get to your destination.
A BMW K1200LT would be a great choice for 2 up.Handling is nimble in the twisties but uber comfort for you and your SO .3-5Ks can get tiresome on less comfortable bikes.They're going cheap now as the 1600 has eclipsed it but still quite a great bike on it's own.You can easily find one for 5-6K and should be able to get your money back minus a % of say $500.00 or so for the dealership to sell.If it's got all the maintenance up to date,fresh rubber and oil ,you wont have to do anything along the way.Great time to buy in the winter in the NE and you could have a few months to get comfortable with it and set up a dealership to take it.
I bought a VFR in CA years ago for a tour in Ca, then left it a local dealership(prearranged) to sell on consignment.I got a check a couple weeks later and the tour cost me a couple hundred dollars after I got my money back.
Much cheaper than renting and you can ride the bike like you own it(you do) and not worry about mileage or nicks and scratches.
