Anybody have any experience with the factory supplied heaters in a Logan or Trails West? Looking at a new Logan trailer and wondering if I need the new 70,000 BTU Hot Dawg heater? It is only available in the 2019 and apparently is now standard in the Zbroz edition. Is the basic 40,000 BTU heaters these come with enough to warm the trailer? I want to be able to hang out and sleep in this trailer at times, with young kids. Just wondering if the extra money is worth it for the dual heaters?
