Then it messes up the back of my sleeper.

Or running a long horizontal of flex (make it run it under the truck and then backtrack if you have to) to the verticle, it would have more range to move around.

I had plenty of flex pipe under there, but I think the problem was it was welded to a very thin, very small exhaust pipe that was never designed to have stuff welded to it, and therefore it got weak.
I put the flexible hose on this morning (finally), and gave it a short test run. The exhaust is definitely going up the stack, as the stack was getting nice and warm. I smelled no fumes standing next to the generator, so if there are any leaks, they are minimal (I expected some leakage because the hose is 1 1/2", and the muffler tailpipe is 3/4", so it is kinda squished around the tailpipe). The noise is at a respectable volume, and the box is staying nice and cool (I couldn't get the temp in the box above 75 degrees - it is 65 degrees outside). The generator was staying at 112 degrees, which leads me to believe I have decent exhaust flow. When I had that 90 degree bend in it, I was getting temps upwards of 165 degrees.
Now the real test - will the exhaust system handle moving down the highway.
