Solar or not to solar
We have a 2000 LTV with a basic solar setup.
80 watts of solar, roof mounted with 3M adhesive, charging through an 8 watt regulator direct to a single 27 size deep cycle battery.
We can dry camp for extended periods in sunny areas without driving using limited furnace, unlimited water pump, LED lighting, cd/radio, and small 125 W
inverter. In poor weather we have never encountered unusable power for as long as 4-5 days.
Very simple, easy to install and inexpensive. Much better than the Onan we had in the last LTV.
A lot depends on your lifestyle and the amount of gadgets you require to keep you happy.
More solar would not be a waste, but 80 watts seems plenty for us.
