When the OEM Sharp MW in our motorhome failed, instead of paying $300+ for an "RV" replacement, I found an $88 Hamilton Beach 1000 watt MW at Walmart that was the exact same height and width. I easily transferred the vented surround front panel from the Sharp to the Hamilton Beach, and with just some small shims to get the height just right, installed the unit using the original screw holes in the cabinet frame. That was about 6 years ago, and the low cost unit is still working perfectly no matter how many times we've driven over the rough sections of I-88 in NY and I-81 through PA...
