If you like diesels, a Ram 1500 Ecodiesel paired with an Escape
5.0TA would have plenty of margin and the added towing stability of a fifth wheel set-up. But you'd be left driving a pickup when unhitched.
Escapes are lighter for their size than the Oliver
but lack the high-end features: aluminum frame, insulated double hull, top-drawer hardware, four-season package. They are nice trailers nonetheless and a very good value.
Airstream... Hereabouts they're known as SOB- some other brand.
