Did it fit through the door, or the window?
Great job. Have you already upgraded the inverter and or solar system? The standard alternator is probably 175 to 250 amps with your engine, and that is plenty when you are moving around. With enough solar, then you can stay dry camping weeks at a time, and not use up all your propane.
Solar panels have come down a lot in price recently, check out this website. You should call them to ask about the panels, they do not spend a lot of time updating their website with current model numbers and prices.
SunElec.comI would be picking out 100 - 150 watt panels and a MPPT controller. Make sure that you have room for them on the roof first. 250 watt panels are way to large surface area, and would take up to much space.
