I have been meaning to post this for awhile. But I have been real busy. I went camping at Capital Reef Utah at the end of September. I didnt take a generator because it was cool enough not to need the A/C. I have a solar panel that usually can keep the camper batteries topped off. Unfortunately we had mild days with overcast skies. The nights where cool so the Heater was running at night. After the third night the batteries where really low. There is no electric hookups at Capital Reef. What to do ? Remembered A/C outlet in truck bed. Luckily I had put a 110v 3 prong to 2 prong adapter in the compartment when I first found out it was only a 2 prong adapter. My biggest gripe about my Ridgeline! I also had in my camping gear a 30amp to 110v adapter. So with the 2 adapters I was able to plug camper in bed of truck to charge the batteries and an run the inside lights in the camper while cooking breakfast. I did have it set to 400watt while the truck was running. Only took a little over 2.5 hours to top battery off. And it was way quieter than all the people around me using generators ! Its good to know I now have another method of getting electric to the camper besides solar or a generator ! Put that 110v 2 prong to 3 prong adapter in your truck now. You may find other uses for it like I did by accident !
