Types
RVs can be either trailers that are towed by vehicles or vehicles that can be driven themselves. Most RVs have one level, but there are also some with two levels. To save space while traveling, larger RVs often have slide-outs or canopies that open up when parked. RVs that can be driven can be categorized "motorhomes", which will have the engine in front, whereas some have engines in the rear. Those with rear engines are called pushers. Generally, pushers use diesel fuel, while pullers use gasoline, thought this trend has change in modern times to include more diesel options for front engine RVs.
