Silicon Valley Region Shop for Convection Oven Replacement?

Class A full-timer currently in Monterey, CA about to head north on the 101. Needing to have the microwave/convection oven replaced, potentially adding outside venting. Curious if anyone has experience with RV shops between here and San Francisco you'd recommend for this potentially "invasive" project. Some mods may be required based on the way the new oven mounts and of course the venting means cutting a hole in the wall! :E Needless to say, not a job I'd want to trust to just anyone.
