Tons of great advice pros/cons, my 2 cents is check the drivetrain, airbags, u-joints, shocks, brake lining and all associated brakes parts, airlines, etc. like mentioned above having a good sized budget for repairs/preventative maintenance, like having all engine water hoses, belts etc. items that would leave you on the side if the road replaced.
Do what your gut says!
Good luck and safe travels.
