Glad you found Roca Azul. I didn't have time to look for a link to send you this morning.
You may have had an address for the PAL RV Park in Ajijic and it wasn't updated because it is now a high density housing development, known as 'El Parque.'
I think there may still be an RV Park on Route 15 on the west side of Guadalajara; not sure & haven't heard about it for years. Of course, I no longer have a motorhome, so I haven't looked.
If interested, the following might help:

"STREETS OF GLASS", by Robert Glenn, is an entertaining true account of a
couple who decide to retire to a lake in Mexico, blessed with cool summers
and warm winters where it only rains at night and the sun shines every day.
There are bumps along the way, problems to solve over the years, a new
culture to experience and adjustments to be made. The author provides
insight and guidance for any reader who might aspire to join the thousands
of Americans, Canadians and others who have chosen to live out their
retirement years in the central highlands of Mexico. One critic says, " The
book is informative, humorous, thoughtful, well written and easy to read. It
captures one's interest and never loses steam." This e-book is available by
sending $12.00 (check or international money order) AND your e-mail address
