Venting Burner and exhaust pipe

I'm thinking about putting my Landa Hot Water PW inside of my trailer or Van. Would it be alright to vent the burner and the exhaust pipe together thru a large pipe that would go thru the roof of the trailer/van? IF I do this would my Powerwasher be compromised in any way?

Thanks

As long as you do not restrict the flow of air from either one of the exausts you will be ok. Make sure the pipe is as large or larger than the exhaust vents. Don't put any bends or elbows in the pipe from the burner.
