I believe you are correct about only one compressor, I’ve not seen a second one. However I now realize an Elite II is not in my future. Back when I bought my last boat I had to buy a new vehicle to tow it. I’ve since recalled that I did a lot of calculations, weighing the Explorer, boat, and then the boat connected to the Explorer. The GCWR forthe Explorer is 12,000# and the Explorer alone is 6,000#, which only allows me to tow 6,000#. As I would be traveling 6 months/year and carrying a lot of clothes, supplies, etc. an Elite II would be too heavy. I don’t have a lot of miles on the Explorer, and I just could not bring myself to buy a new truck. I guess I have to go back and look at a Lance, which I believe is better quality than even an Airstream. ☹️
