Raptor toy haulers strike the perfect balance of residential comfort and flexibility to deliver no-limits adventure that evolves as you do. We get it: you want it all, and you know what? We think you deserve it. That's why we want to talk about Raptor Toy Hauler RVs. These spacious RVs have all the space for everything you want to bring on the road, combined with all the comforts you'd expect at home. This luxury toy hauler, built by Keystone, has enough features to please every member of the family. With each of the many floorplans available, you get a roomy garage for your toys plus a mobile, modern farmhouse feel with a large kitchen, a bathroom, and living areas filled with natural light. We love the high resale value on Raptor rigs, which come equipped with the latest technology. You can auto-level your rig with the push of a button, and zero-gravity doors keep it simple to set up camp and enjoy your time away. Each of the Raptor Toy Haulers features a hefty 106-gallon freshwater tank and wastewater tanks ranging from 44 to 88 gallons, so you can go off-grid with the family for quite a while. They sleep between seven and nine people, leaving plenty of room for more guests.
