As others have said the road is in decent condition. There are a couple sharp water bars that sneak up on you so don't drive too quickly. The rocks which were on the road have been moved to the side and now it is much easier to pass through. Made it up to the end no problem in a stock Jeep Wrangler.
As has been said, Ford Mountain FSR is the real problem. If you can get past that then this spur is easy, albeit a bit bushier. There's a couple of boulders to navigate around, which may be finicky in wider vehicles, and a few small cross ditches that may sneak up on you, but all in all it's in decent shape to roads end. Nice alternative to starting hiking from Chilliwack Lake Road.
Same condition as Heath's report, I'd just add that about 400m from the driveable end there is a "shooting gallery" with a big plywood sheet & target, just past this there's a few rocks on the road that need to be maneuvered around.
Compared to the Ford MTN FSR this road is in great shape. No washouts to compete with and is actually pretty smooth. The last 200m of the road is completely overgrown and eroded. There is room for 4 small vehicles to turn around and park before this. This is a great starting point for Williams peak compared to Chilliwack Lake Road, if you can get past the gatekeeper Ford MTN FSR.
