Hubby and I did it by ourselves.
Above the micro in the cabinet you'll find the 2 bolts that are holding the microwave in place. We removed those (I was more of "the hold it in place" person). We then tilted the micro forward a bit and lift it off the plate mounted to the wall...which has a lip that the micro sat upon. Just be careful, you'll need to reuse that plate. Then just lift it off and out...It did take 2 of us, cause that micro is large and bulky. The new oven will sit upon the plate just like the old oven did.
We then used the template that comes with the new oven to re-drill the holes. We also had to add another piece of 2 x 4... for added support (if i remember correctly, we cut it in 1/2 making it 2x2. I believe we mounted the 2x4...or 2x2 using wing nuts. We reused the bolts that mounted the microwave that came with our camper. One thing to make sure when you're mounting is to place the oven wall snug against the wall of the cabinet near the fridge. If too close to the pantry wall, the door of the oven will rub against it. We had to adjust ours.
The electrical cord is mounted it a difference place on the new oven, but you have plenty of cord in order to plug your new microwave into the outlet.
The most challenging part was changing the venting (which we did before we we started mounting the new oven). Our oven came ready to mount with venting outside. Getting the back off the oven, changing the vent fans, and putting it all back together was tough. Neither of us are particularly mechanically minded, but we managed. If you're a pro at honey-do projects, you'll probably have no problems.
The directions were great. Pictures and all!
Hope this helps
