This is my 2nd Opus trailer, and I'm the original owner of this OP4. I've towed it effortlessly with an 06 Tacoma and more recently with a Tundra all over the West Coast and Rockies. I've made a few key upgrades over the years. The propane heater with adjustable vents keeps it toasty inside. There is an EcoTemp hot water box with diverter to outdoor shower or kitchen. It usually mounts to the rack, and has an Ironman shower tent attached to the rack for quick drop down privacy. There is a cabinet for a toilet, but we just use it for extra storage. There is a Dometic 50L fridge / freezer on sliding tray in drawer. The fridge drawer is big enough for a larger fridge. 4 burner stove, with an upsized regulator capacity, versus the factory ones. 40 gallons onboard water in stainless steel (not plastic) tanks with diamond plate skids on this model. I drain, blow out, and winterize the water system every year without chemicals.
.
I've upgraded the batteries to Lithium 300ah with a Victron IP65 charge controller and monitor (app compatible). I've gone a week and barely use up that capacity. The lights are LED and dimmable, and the Dometic fridge is very efficient. There is a Shore Power connection, and a Zamp solar port, although since switching to lithium i haven't needed solar any more. A We-Boost mount is on top of rack when vertical, and wires pre-run for quick hook ups.
.
This trailer comes with the hard to find 'Sun Canopy' that inflates simultaneously with the main tent - and the main tent wall can actually be unzipped between the two areas to open up the view and breeze (sample pic attached). The hitch has the DO35 3-dimensional articulating hitch and the ARK750 jockey.
.
The storage bin organizers come with the trailer, but the contents in pictures stay with me. There's 2 jerry can holders, I'll include one NATO jerry can. The other I put a LifeSAver water filter jerry, on the odd chance i need water and the source is questionable (highly recommend). Also included is the Nemesis-Pro wheel clamp lock, for when you are in the urban jungle.
.
The pop up rack is fantastic! I will include the surf/SUP rack pads if desired, as well as the water proof travel bag where I keep a campfire grill and other odds and ends. There is a Yakima flip up 2 bike rack on the spare tire. The trailer is weather protected with an included factory OPUS 4 rubberized cover, far better than the amazon knock offs.
.
My favorite thing about this trailer is how spacious and bright the inside is, and that you can use the kitchen for lunch even if the tent is packed up. Secondly, is how it can handle any environment with ease. It's a swiss army knife of capability, good eating, and all your hobbies in one efficient package.
.
What it needs? not much...tires have plenty of tread, but they are original. There is a small dent by rack mount with special thanks to a Montana bush track.
.
Why are we selling? Our kids in college, and after 11 years of OPUS traveling, we wanna downsize and explore Van camping. If you're still reading thus far, my 2020 Tundra Pro will also be up for sale for a package deal.
.
There are great videos on youtube about the OP4 being tested in the Outback with a firetruck hose, helicopter backwash, a baseball bat, and some brutal Outback tracks, as well as other people's BLM and BDR routes stateside.
