Very important that your tent be a color that will blend reasonably well. Dark grey or brown is always good. Even these will sometimes come with brightly colored markings. Not good for stealth. Lay your bike down and cover it to prevent reflections from headlights. Beware of reflective markings on the panniers. Light in the tent will make it stand out at night. I carefully use a book light to read with.

I avoid stealth camping when ever possible because because it's harder to relax. Never been caught, but have been seen a few times. 99.5% of people passing could care less. Cops are interested because they are usually bored and catching a camper gives them something to do.
