Last year we stayed at Coconutz RV Park in Cuyutlan, a few minutes north of Tecoman just off the 200D before the toll booth. We drove up to Colima from there in the Jeep. If I recall it was about hour's drive to Colima.
Coconutz is certainly doable in a day from Playa Azul. We are in Zihuatanejo and will likely head there from here, planning on a fairly long day.
Coconutz is a nice park with concrete pads and 30 A service. They might even have 50A but am not sure. Super clean washrooms with hot water showers. No wifi. but poor wifi is available at the nearby Fenix hotel.
From there it is a days drive to PV. According to our log book, last year I left Coconuts at 8:30 and arrived in PV at 2:15 including a fuel stop in Barra de Navidad at 10:00
