I would go slow & easy. If it gets a little dicey, stop before you are really stuck & wait it out for another day or so. A lot easier to keep from getting stuck than to have to get unstuck. Not to mention $$$$ for tow & possible damages. Remember, "patience is an honest virtue", "haste makes waste". If you absolutely must go and you are not sure about ground conditions, think about having someone with a heavy duty 4X4 or maybe tow truck hook up a long tow cable and give you some assistance pulling to get you through the muck before you get it completely wallowed down. Assistance vehicle should try to stay on good ground during the procedure. I have used corrugated tin roofing panels to build "road" across soft sand for pick ups before. Placing tin down then driving up on it. Carry the pieces from behind to the front as you drive across 8-10 feet at a time. Not sure how it would work on a heavy coach in mud though.
