Meet your host, James

Thank you for visiting!
My wife, four kids and I have long wanted a camper to take on summer camping trips. We particularly enjoy camping off the main road and the OP4 fits our needs perfectly. A lot of the time we haven't picked out an exact campsite until arrival and adaptability was an important feature. We have thoroughly enjoyed our trips to Cedar Breaks and the Bear Lake area. We happily extend our camper to you to create incredible memories and strengthen bonds between friends and family.
Go enjoy the outdoors!

James was great to work with. Camper was super easy to tow and was very nice to have at our campsite.

Had an amazing first experience with outdoorsy and the Opus 4. James was patient explaining it all to a newbie and answered questions during the trip. He was flexible with timing on pickup and drop off. I can’t wait to rent from him again.

Awesome experience. The Opus towed really easily, and handled some decent BLM roads in Grand Staircase Escalante (Cottenwood Rd) and Capitol Reef NP. Still was able to achieve impressive mpg going 70-80 mph.

Great camper for families

James was very helpful and always responded quickly! The trailer was clean and in great shape. We stayed completely dry and comfortable when we met several days of rain on our trip. The trailer comfortably fit 4 adults and two children. I'd recommend watching YouTube videos on the OP4 before your trip so you can speed up the hand-off and use all the trailer features with confidence. It's an easy set-up and take down if you know what you're doing. Expect a great time!!

James’s answer

Watching YouTube videos is a great suggestion. I will recommend this to everyone in the future. I'm glad you had a great time!

Q.What flexibility is available for picking up and dropping off the RV?
There is some flexibility and this will be addressed uniquely for each reservation. Please reach out for any questions.

Q.What is required to tow this camper safely?
Requirements: 1) 2-inch receiver, if you have a larger receiver we can make this work, simply let us know your receiver size. 2) 7-way wedge connector (see pics) 3) Trailer brake controller

Q.Are there any special tricks and tips that would help with operating the RV easily?
A copy of the manual can be found at https://www.opuscamper.us/op4-manual/ A walk-thru of camper functions and set-up/take-down will be explained at pick-up and will take approximately 20-30 minutes. This is to ensure the safe operation of the camper.
