the first thing to make sure is that you have a digital TV or a digital converter if not. assuming you have that, since it worked in another RV. there should be a Antenna booster located in the RV somewhere, usually in the bedroom.
Most airlines in the United States, including American, Delta and United, allow carry-on bags that are no more than 22 inches long, 14 inches wide and nine inches high. Southwest and JetBlue accept a more generous 24 inches by 16 inches by 10 inches, and JetBlue even adds a couple more inches for cabin bags flying on its Airbus A320 planes.
Re: Delta and the new carry-on size restrictions - experiences? Sep 1, 2015, 4:08 PM A couple of months ago, IATA announced a new initiative to reduce the recommended carry-on size from 22 x 14 x 9 ins to 21.5 x 13.5 x 7.5 ins (55 x 35 x 20 cm). Most US airlines ignored this proposal, and AFAIK it never made it past that stage.
