Worth buying a Hymer Sunlight and upgrading it?

For me, the unit is pretty close to ideal. I don't need heated floors or other stuff. The main thing I care about is having a good A/C in the Texas heat.

The next step up for the same floorplan as a variant of the Winnebago Travato, and those are upwards of 80k, so I would pay 60% more for basically the same chassis if I go that route. The "engine generator" also comes in handy, especially if I have a Honda 2000 watt model that I can pull out when boondocking.
