I've got to disagree with OldB. If you do a good job and make it look professional I'm not sure it would effect resale. I HATE the pos range in my Springdale. The oven is useless. I just bought a PIC and have been playing with it. I am considering something like you want to do with these changes: pull crappy M/W out and replace with decent convection combo. Yank stove out and build recessed box to hold 2 or more PICs with cabinet underneight. Admittedly I keep my TT in parks that have good and plenty power.
