Sounds like you've found a good fit using a TC for your outdoor needs. We too had dirt bikes when our kids we're young, but used a TT at that time. The furnace in our Komfort 19' trailer actually sounded like a gas turbine in the helicopters I fly starting up. Totally unacceptable and made sleeping so difficult that we took the trailer back to the dealer (purchased new from Paul Evert in Fresno) to remedy the issue. They we're awesome in that they replaced our jet engine with a larger and much quieter unit ( don't remember model) at no charge to us.
The reason for this background is to illustrate that you don't have to put up with that annoyance. Our current Arctic Fox 996 has a Suburban NT-20SQ furnace (20K BTU) that works great and is quiet enough that we sleep just fine. I urge you to find someone with a unit like ours to listen to it to see if it will work for you.
Welcome to the TC club, they're a very versatile unit and yes, having a hot shower at the end of a day on the trails is priceless!
