I routed my exhausts that way because my driveway has a steep pitch, and I wanted to avoid flattening the tips when transitioning from the road to the driveway.
If you’re interested, I can post some photos. I brought the generator exhaust out the right-hand rear side, and the Webasto exhaust comes out under the Webasto door. It’s not a perfect solution, but it prevents both from getting damaged on the driveway.
Roger Foster has his exhausts exiting on the left-hand side as a pair, angle cut, and they look great while being well-protected. Maybe Roger will share a picture as well.
