Same rig, same mileage, same options but adding a 6 foot slide-out, adds $1470 for a total of $52,499
Actually Ron, according to NADA, your rig with a slide would have originally retailed for $83,113 and if selling today would be $63,929.
When selecting the original model you either choose a 2350 non-slide or 2350 slide. For some reason NADA values a slide if added as an option at only $1,470 but NADA does not treat a slide as an option on any Phoenix Cruiser. NADA identifies each Phoenix Cruiser as a separate model depending upon non-slide, slide, double slide.
You make a very good point that people have to look at these guidelines very carefully when determining the value of a motorhome.
