Age is not the issue. The greater concern would be was the tongue cut off and were the axles removed when it was first set, as is common practice.
The tongue is the most critical, as if it were cut off, a replacement would have to be welded on, driving up the cost. The axles are common fare for MH movers, and they carry enough on their transports to attach temporarily to the home being moved.
Look around the home, note if the tongue (hitch point) and axles are not present, then call a home mover to advise what you may expect.
You can easily know if your mobile home is too old to move by assessing its exterior and undercarriage. The old mobile homes will always have a damaged floor, walls and roofs. They could literally fall off or apart on the roadway upon moving or transportation.
