I must say that the gen-turi is one of the few aftermarket pieces of equipment that works as advertised and does not require modification or re-engineering to install and function. For what-all is in the kit the price seemed reasonable on sale at Camping World. Even has a zip up baggy to put everything in.
I was amazed at the reduced exhaust smell around the coach for ourselves much less the neighbors. It also reduces noise considerably....outside and inside the coach.
I struggled with drilling holes in the coach but after making sure nothing was behind the area I did pop-rivet the small metal holders gen-turi provides to attach the support straps to. It does make it easy to install and they are nearly invisible if you paint them the appropriate color for that part of the coach. No worse than the hold-downs for the awning straps.
Get the gen-turi extension pipe to clear the higher Entegra roof line.
One other recommendation is to purchase a windshield installation suction cup tool. Stick the suction cup(s) to the side of the coach high up and bungee the top of the Gen-turi pipe to the handle and/or isolate with a piece of foam pipe wrap. Stabilizes the tall pipe and reduces swaying and load on the lower pipe and lower support straps.
Highly recommended to have one on board. I even put ours on one night in a truck stop after a truck pulled in and parked on the left side by the genny exhaust. The driver actually came over later and mentioned the Gen-turi pipe and thanked me for the consideration.
You could even get carried away and camo the Gen-turi pipe to the coach colors and no one would ever notice it.
