There is lots of threads about converting over to a double recliner situation, or something similar... In most cases these conversions have NOT been done on a 28' as it have a lot of stuff under the "L" part of your sofa. (IE: hot water tank, convertor/charger, Woofer, and inverter). These items are very hard to move or hide so doing a conversion to either a recliner sofa and recliners themselves is going to be very hard to do.
I looked into this with the Service Centre folks at the factory and they felt it would be very hard to achieve a conversion that we would be happy with. That said, I don't think this issue is dead - its just a lot harder to do a conversion on the 28' than it is on other models.
Hope this helps
