Thanks for the replies! It was nearly 60 degrees at the Coast and sunny, with not too much wind. A truly beautiful day. We had a spot overlooking the ocean which was spectacular. Got cold at night, though (we weren't plugged in and the van doesn't have enough battery juice to last through the night we found out). Still, it was a great time. Yes, the PW van does have lithium batteries, ours has one solar panel, and a generator. We wound up starting the van about 7:30 in the morning - I was unwilling to start that noisy generator early on a Sunday. I was impressed at how comfortable the bed was - I didn't have high hopes, but it was actually quite nice.
Thanks again for the replies - I have been reading a lot of threads here on such things as what to do with the spare tire (ours is currently under the sofa and hogs nearly all that space), strategies for getting the batteries to last through the night, and what to take/not take along on a trip......
