Was at the factory last Thursday and Friday. Didn't get to see the new Transit 2100, because it was staged over at the Elkhart RV show which got postponed until next weekend due to rain/mud. As I understand, it's not yet a production model--but a prototype that may be placed in production depending on the reception it receives. I did look at the new 2351D which is being built for the Hershey show in September. Places the corner bed on a second slide-out to the passenger side. Also incorporates the Truma Combi unit that combines the furnace and water heater into one unit. That was essential because the furnace had to move from beneath the corner bed to accommodate the new slide. The Truma Combis have been in use for years in Europe due to more focus on "green" issues, and are now being used in some other US units (some Winnebago models for one). Speculation is that the new 2351D could become their second most popular model (behind 2552).
We had 3 Rialta’s and loved them. Would have bought a new one if they still made them. Would love to see a similar floor plan - with slide and decent bathroom shower.
My early 2350-S has a huge storage compartment under the bed because the furnace and converter are under the refrigerator, so it will be interesting to see what they did with the new 2351-S.
