The Swift is a down grade from a standard Jay Flight.
The biggest differences are the lack of in floor heat ducts. They are above floor, flex hose ducting. This robs storage space.
The A/C is ducted but is not thermostatically controlled. It's controlled on the ceiling unit itself, meaning the fan will always run even when the compressor cycles off.
Storage compartments have less room because of the above heat ducting as well as under the sofa (at least on 26BH).
Under queen bed storage isn't sectionalized from exterior storage.
There is no 30 lbs propane tank option, only standard 20 lbs tanks.
Also smaller fresh water tanks as well.
Also, while this Swift looks lighter than the standard Jay Flight, if you add on the options, they are about the same weight.
Now here's another big difference. The Jay Flight Swift 264BH (26BH clone) only has a 6500 GVWR, for less payload than a 26BH. The 26BH has a 7500 lbs GVWR.
These are the big differences which were very important to me, especially the propane and fresh water capacity. I was upgrading from a 2008 Jay Flight 19BH. At that time, the lower end standard Jay Flight had these options (except ducted AC that was offered in 2009). I didn't want to downgrade in amenities from what I had.
Now there are still much more differences mainly in luxury amenities but those were less important to me.
I don't think offering a Jay Flight Swift to replace a standard Jay Flight is a true replacement because of all the feature differences.
However floorplans are the same and if you camp in warmer weather at Jellystone or KOA parks that offer full hookups, the differences in tank capacities will have less meaning.
I don't know why the difference in heat ducting as it doesn't really seem to be a cost saver and different tooling make it seem more expensive to me.
