I'm planning a trip leaving from Chiang Rai end of this month crossing in Chiang Khong to Luang Namtha -->Nong Khiew-->Phou Lao in my 4x4 truck. I've done this before a few years back, but am wondering about the present condition of 1C? Second, wil be going from Phou Lao-->Phonsovan (done this before should be no problem). However from Phonsovan I don't want to take Highway 7 west to 13 south to Vientiane. Would like to head east out of Phonsovan on Highway 10 to Thoum than drop down south what looks like a small road on GT Riders map to Viang Lang. Than head west to Xaysomboune. After Xaysomboune hang a left and go south on what looks like a bigger road to Langsane and continue to Thabak where I can hook up with Highway 13 back into Vientiane. I'm no newbie; been riding bikes/trucks through Laos, Thailand, Cambodia, Vietnam for many years. That said I don't have or would want to use a winch or have to dig myself out. So is this trip doable ???
