X2 on no Pergo. What every you do choose, get a small sample and stick it in a glass of water for a month. If it doesn't swell up, then it is a consideration. Specifically my neighbor installed Pergo. Water spilled on it, ran over the edge, and wicked under the floor. This caused the floor to swell up, and eventually buckle. A motorhome is very vulnerable to mishaps. This means the products you use must be water proof, and much more durable than what is required for a stick house.
I, too, have 3/4" real cherry planks which we installed only recently. Nailed & glued. Yes, we are concerned that it may have problems with changing temperature and humidity, but it is beautiful for the time being. Hope it stays that way.
