I bought one of these but am having problems hooking it up.  The hole in the Kipor is to small to allow the adaptor pipe to clamp on to the exhaust pipe.  Is there a way to extend the pipe so I can clamp on the adaptors?   I don't want to make the hole in the generator larger.   Can I just clamp another pipe on to the existing pipe or do you think it will cause a problem?  I can't lift the generator by my self so I keep it in the truck and want to vent it away from the sleeper.
