Excellent trip photos.
Looking at your RV, based on a Ford E series (350 ?) cab and dual rear wheel chassis, I recall when working my way through U., back in the '70's, I drove a delivery box truck, which had a similar cab and chassis. It had the 460 cube V8 (7.5 litre ), which was quite powerful . Very reliable, ruggedm durable truck, although with that massive V8, it did like it's gas.
