No, I do not have a side mounted BBQ, but I do have a flip down stove and sink built into my camper. Here's the "down side" I see, and this would be 100% true for a BBQ, attached to ANY RV.... If you are parked on a sloped campsite, you might have to use a ladder to reach the BBQ. We were camped once. The parking pad was level, but at the edge of the gravel it dropped down (sloped fast). Couldn't use the stove. From the ground, it was too high. Ended up using the electric skillet on the picnic table (which was also blocked up on the feet). That the one down-side I see with attaching anything to the outside of any RV. (Level camp spots ... no problem.... hills ... better bring a ladder).
