From Wellington would definitely be a no-go. Come in from the west, either from Huntington or from just north of Castle Dale, both off UT-10. It's an easy, easy drive -- without a trailer you can easily cruise at 50 mph on most of that dirt road.

I’ve gone from Price to Jurassic National Monument then to the wedge with my 22’ TT. Good dusty dirt roads. No problem. If it’s muddy I’ll bet it gets greasy like a lot of desert roads.

I'm confused. From Wellington it is a short hop east to hwy 10. Hwy 10 is a great road and I think the speed limit is 65. I would take about 35 minutes to get to Huntington. Like Grand Adventure said from there it is an easy drive to The Wedge Overlook. Although gravel, the road is hard packed and there are no problems at all with it.
