The Swift usually has less amenities... and the design is less luxurious (if I can use that word!!!)
For example, I have the 28BHBE JayFlight...the same floorplan is available in the Swift, but the decor is not as elaborate, there are 2 windows less in the slideout... and the weight of the Swift is lighter...
Best thing is go check both out...Swift and JayFlight.... compare the interior and features... the weights and the price...and then you can make a decision!
