Fueling up the Winnabego Horizon 40
I bought a 2018 Winnabego Horizon 40, since I did not buy new, I did not get the full walk around. I stopped yesterday to fuel up, I had a little less than a half tank. I tried to fill on the passenger side but that side had the fuel full up to the cap. Is it two separate tanks? Is this a separate tank for the generator? I can't seem to find the answer.
