Montana 3400RL slide outs

[daveinaz]

I know that all four slide outs are hydraulic on the unit. I also think that the main, opposite, and kitchen slide-outs are through the frame hydraulic slide-outs. But am I correct that the bedroom slideout is a through the wall slideout (using Lippert's nomenclature)?

I'm guessing they all use the same type wiper and bulb seals, correct?

Thanks.
