I went ahead and ordered a TCS Chief 2 with a diesel burner, 175 gallon waste tank, electric reel, etc. If this works out good (so far I’m very impressed with their service)I will definitely report. I know there’s a lot of people out there scrambling to get an El Diablo. As far as footprint in a van and potential heat, the TCS machine might be comparable. We will soon see. Thank you all who gave me advice in my other thread and helped me come to a conclusion.
