No difference running a generator at night as the same as in the day! If you can run your generator 8 hours in the day, why not 8 hours at night? I see no difference at all...
Daytime heating/solar radiation keeps the air moving enough to dissipate any CO accumulations. Air tends to be more still at night and inversions may develop. CO
MAY build up in low or sheltered spots at night.
If your rig or the gennie is not setting in a low spot, or there are any night breezes at all, the probability of any significant CO accumulation is negligible. As long as the exhaust is not sitting directly under your open window you should be OK.
There have been some studies showing morning CO accumulations in campgrounds where several campfires have been smoldering all night. The CO did not rise to the level of human health risk, but there was a measurable increase.
