Depends on how high you are talking. My truck camper Ginny is in the rear, passenger side, so I attach my Gen-Turi to the vertical ladder supports. It extends about a ft above the roof line. If I wanted to extend it another 3 or 4 ft higher, I would install some support wires to the extension. Not sure why I would ever want it that high though.
The Gen-Turi is not a direct connection from the generator exhaust pipe, but has a break to allow cooling air to be sucked into the exhaust stream going up the vertical pipe. In theory, in very cold weather, with a taller extension added on, the warm exhaust might fail to rise out the top of the pipe and try to settle down, causing the exhaust to come out at the bottom where it joins the generator exhaust pipe. Not likely but I have seen it happen with wood stoves with non-insulated stove pipes in super cold weather, as the smoke cools to the point it stops rising in the pipe and the stove stops drafting. Smoke filled house is the result.
