where to go

I'm assuming that the 11 day restriction is because you're still working, but you won't be forever.
This is just a suggestion. Figure out how far you can comfortably drive in a day. Let's say 400 miles. So, break out a map, draw a circle with a compass at 1200 miles. That becomes the area where you can drive 6 days and camp 5. There are a lot of places in that circle. Yellowstone, for instance. You can't see all of Yellowstone in depth in 5 days, but you can see where you'd like to re-visit. A 1200 mile circle would take you as far east as St. Louis, north and south, well into Canada and Mexico, and about half way to Hawaii going west.
Once you figure out the general area you're going to visit each trip, get on here and ask for suggestions. Somebody on this forum has been there - probably several. Adjust your circle for how long you like to drive in a day.

What about NM? Northern NM is beautiful, Angel Fire, Red River,Chama. You don't say what time of year your talking about, but if you go farther east before the heat sets in Red Rock Canyon state park in Hinton OK is pretty cool. Also we visted Branson and stayed for a month had a great time in May, although it was tornado season, for Bluegrass and Barbecue at Silver Dollar City, stayed at their RV park the Wilderness. Best deal is to buy their season pass and it pays for itself in the first two days!

You live in Utah & waht to go elsewhere??? Like my granddaughter says...
"wut-evah". lol. Havin g said that, where have U been/seen/done in Utah/Colorado? Have you done 4x4 Jeepin, in the Moab area, on the Shafer trail switchbacks? White Rim trail? Gemini twins trail? 7 mile rim trail? How about Rt.12/24 between Bryce canyon & Capital Reef? Have you seen the AMAZING views of Long canyon on the Burr trail? In Colorado, have you done any 4x4 Jeepin on the trails between Silverton & Ouray?
If not, you don't have time to leave Utah...you still got ALOT TO DO!

You'd almost need more time than 11 days to get anywhere decent east of Colorado unless you like flat, farming land (which can be beautiful). I would suggest northern Arizona or northern New Mexico - lots of neat places.

Another vote for Tetons, Yellowstone, and Glacier.

Another idea...Page/Lake Powell, Grand Canyon, Sedona/Flagstaff area

Yellowstone if you haven't been. Including Grand Teton, 11 days from Utah would be adequate time.

My pick would be Alberta (Banff and Jasper) but that's a long haul. It would be 2-3 days just to get there. What about Arizona? Love the Senoran Desert and the Sedona area.

How about coming into BC and Alberta

Lots to see and do and with 11 days you could see most of the two western provinces.

You would have plenty of time to do Yellowstone and Glacier; or Yellowstone and Tetons; or Yellowstone and the Black Hills. The theme there is to do Yellowstone. If heading west, Yosemite and Sequoia would be on the list if you have done them before.

You could cheat a little and look at the Adventure Caravans website to see where they go. They spend a month in September visiting the National Parks out west. Maybe there's some place you haven't been.
