We have a 38' Fleetwood Expedition diesel and we tow a 4 door Jeep Wrangler. We are thinking about driving from Whistler to Lillooet on Highway 99 but have heard it would be a tough route with our RV.
Has anyone driven this route? If so, how was it? We can anyone recommend any RV parks? We will start out in Vancouver and end up in Kelowna.
Thanks in advance and have a great day!

from what I know its a pretty winedy twisty road that got some pretty steep grades like over 10%

heres one review I found
Duffy Lake Rd. AMAZING!! This is a hidden treasure. One of the most scenic drives I've taken. The road, at least most of it, has recently been repaved. Twisty, turny, up and down, winding through valleys, then up 13% grades to the top of mountain passes.you cross several temperate zones along the way ending up in Lillooet, surrounded by sage brush.

many many years ago I lived in Bralorne but this road was only a goat trail then
