If a hotel can have bed bugs so can your RV and your house. From wikipedeia:
Cause[edit source]
Dwellings can become infested with bed bugs in a variety of ways, such as:
Bugs and eggs inadvertently brought in from other infested dwellings by visiting pets;[15] or a visiting person's clothing or luggage;
Infested items (such as furniture, clothing, or backpacks) brought in;
Nearby dwellings or infested items, if easy routes are available for travel (through duct work or false ceilings);
Wild animals (such as bats or birds)[16][17] that may also harbour bed bugs or related species such as the bat bug;
People or pets visiting an infested area (apartment, subway, movie theatre, or hotel) and carrying the bugs to another area on their clothing, luggage, or bodies.
I think everyone is overly hung up on Hotels and bed bugs. If you travel, and see other people in the vicinity you can get them.
