I did downsize from godzilla to newer V-10 and that is where some of cost savings is. Didn't want to buy a new truck since we don't use it very much. Our current truck is a 99 that we bought used in 2004 with 40k miles on it and it now has about 78k miles so just a few thousand miles a year.
The used trucks I was looking at were king ranch and lariat so that is why they cost more. My current truck is also lariat.
We are in our 70's and hope to get many more years of camping. We go by ourselves most of the time but once a year have a family campout with kids and grandkids which everyone enjoys.
I am fit so dealing with the camper is not an issue but recognize it would be a little easier with the class c.
