We have been up & down the full length of Hwy 1 in our 40' XL towing a Land Rover. It is possable, but there are some very tight spots particularly North of Fort Bragg. I would recommend against it, especially North bound as you are up against the rocks, and there are many blind turns where you will have to encroach into the other lane. If you really want to do it, I would recommend the section from Morro Bay up to San Francisco. It is not to bad, but you will need to take it easy. Hwy 101 gives you similar spectacular views up in Oregon, it is tight just North of Gold Beach but much wider than Hwy 1.
