We recently picked up bed bugs in our 35ft class A and their primary spot is the living room couch/bed.... the mattress isn't removable from the frame to wash or replace, so I guess we'd need to replace the entire thing? Where could I even buy one? We're planning to heat the RV as the next two days are supposed to be 95+, and we're hoing that the outside heat plus a large rented commercial heater (that goes to 140F on its own) will do the trick. We also picked up DE to sprinkle and will be wing bedding/clothing etc... although I'm not sure that's required if the entire RV is being heated already?
