Some but limited experience:

Be careful during mid-day--as the valley heats the air rises and creates tailwind conditions, sometimes quite strong and the airport winds may NOT match the actual wind. I was conservative, if the variable wind looked out of limits at TOD, send the driver to Rifle or Eagle and divert. Everyone should understand and the driver will be waiting at either airport. Or arrange a rental/taxi.

Take your time, if you fly--off a bit to the west of RBL and fly over the valley, you do not need to fly a 6 or 7 degree descent.

Be slowed at Red Table VOR, you don't need to configure, but be back at flap speed.

Day VFR your first time, maybe on your third time, too.

Do NOT circle a jet to runway 33; there's marginal room, but you'll be belly up to a lot of close terrain and doing a downslope landing on 33 (15 is upslope 2%, 33 is down 2%).

Be real conscious to be "on profile", "on speed" leaving about 3-5 miles, going around or a balked landing in close would be exciting, not in a good way, either.

OEI on take-off, go up the valley and transition to RIL or EGE. Doing and engine-out return in the valley would be very risky.

I've gone missed on the approach, I didn't breath until about 14,000'
