Hwy 101 and Hwy 1 (PCH) Can it be done in a larger Fiver?

Recently talked to a guy in a 40' Phaeton pulling a dinghy. He'd just did the portion of 1 south of Monterrey. He admitted that there were stretches where he had no choice but to cross the center divider. The question of Highway 1 does come up a lot. I will continue to respectfully state the following. The RV stays on 101. Use the dinghy/tow vehicle for days trips on 1. Lots of very nice private parks on 101 will facilitate this.
