WOAH! Check out this amazing amphibious RV!

By Cheri Sicard
Ahoy, mates! You are not going to believe this amazing amphibious RV! Is it a motorcoach? Is it a motorboat?


The Terra Wind floating RV can take you both over the road or over the water.

The video below will give you a complete tour of this incredible amphibious RV, the prototype work of designers John and Julie Giljam who now custom-build amphibious RVs for others.

How was the amphibious RV constructed?

Terra Wind construction started from the bottom up with an aluminum boat hull, then a luxury Class A-type motorhome was added to the top half. Inflatable pontoon outriggers keep it stable in the water. There’s even a fold-down 6-foot swim deck in the back.

While it may sound complicated, the rig does most of the work for you. You can seamlessly transition from road warrior to sailing away in under five minutes. Surprisingly, only one engine powers the whole thing.

The only downside? This amphibious RV is meant for smooth water cruising only. No surf or open ocean. Two- to three-foot waves are the max it can handle.

Inside, the coach has the look and feel of a luxury yacht with every convenience and luxury you can imagine. There are residential-sized appliances, two slide-out rooms, marble countertops and teak wood cabinets. There is even a Jacuzzi bathtub!

Watch the video below and be prepared to be blown away. The Giljams have thought of everything a landlubber or a boating enthusiast could want when designing their amazing amphibious RV houseboat.



  1. Well built, he started with the boat and hull, then built a purpose Motorhome with all of the required safety, Coast Guard equipment lights all all, to bring it into not just a road worthy buy full water worthy craft. Yes, create innovation and sound engineering all in one great BoaterHome!!!

  2. I love the forward “out-of-the-box” thinking! Innovation is what has lead the Rv industry from covered wagons (orig RV!) to Winnebago, Prevost, Newmar et al….. I hope this venture is successful. (Certainly would be waterproof!)

  3. I don’t know about the motorcoach but Chevrolet says replace/ regrease the wheel bearing and driveshaft grease daily when operating in water. I just wonder how many times that morfidite is going to be needed to pulled out of the water.So many boat launches in my area give you enough ramp to get the trailer wheels wet and then drop off. I wonder, fully Coast Guard approved and full complement of safety equipment including flares ,life jackets,anchors etc. Don’t plan on buillding one for me or my friends.

    • John (the designer) used to refit as well as operate LARC-Vs going back to the 90’s. He currently builds tour and rescue amphibians for various companies and governments worldwide, many of which are operated on a daily basis. Take a look at some of his other creations –
      I’m his son-in-law. John’s innovation, creativity, and talent have never ceased to amaze me in the 23 years I’ve known him.
