Insulation values in slides

[usandthreedogs]

Hey All, wife and I are thinking of trading up to a DRV soon. Does anyone know what the actual R values of the slides are? Floors, walls, roof etc.
Have any of you seen the actual construction of the slide rooms? I ask this because of previous experience with current RV. was told the slide were well insulated, only to discover while doing a window reseal that there was almost zero insulation! and NONE in the floor. so before we jump we'd like to know, Whats In There?
