As others have done, I recently completed a Victron Orion XS DC-DC charger installation between my 2023 Ram 1500 and 2019 Oliver Legacy Elite II, Hull 514. The attached write-up covers the truck and trailer wiring, Anderson SB120 connection, cable routing, fuse locations, Victron settings, parts list, photos, and lessons learned. I thought I'd share in case it helps anyone considering a similar project. Happy camping! Oliver and RAM DC-DC Charger Installation FB pdf.pdf

The toggles have changed. Ours and likely yours do not have the little blue LED lights showing the ON state like the newer ones. I don't know where to buy them but first jump the two wires connecting to the switch and see if that powers the lights, to be sure the switch is bad. If it turns out the switch is good, look at the connections to the courtesy lights in the streetside basement.

jd, not such a thing as access to below the Pantery into the space behind the battery compartment on my trailer to the. I should be able to fish the center red wire with a scope.

Excellent work, Jeff! And happy to see a new Forum Member share such a great project providing such detail. I installed ours March 2025 and we love this mod more than most! The Orion XS 50A DC-DC charger is the best possible upgrade for charging LI batteries. You need a whole lot of solar capacity and a lot of time sitting around the campsite, fussing with panels, and you won't get anywhere near the average 40 Ah per hour towing this installation will provide. If interested, read my comment re running our A/C all day, towing just 2 hours, using only 20 Ah because the Orion provided most of the power needed. If I towed another 30 minutes SOC would have been 100%! We do have 320W rooftop solar but it was a cloudy/rainy day. https://olivertraveltrailers.com/forums/topic/11177-furrion-chill-cube-–-product-review-and-installation/page/3/#comment-126555 Those of us who boondock 1-3 nights at a time, moving often, don't need much else. Add an efficient A/C and Orion DC-DC charging will allow you to stay cool anywhere/anytime! We added 400W suitcase solar and wish I had saved the money since we rarely use it. We connect our Orion DC-DC charger every time we hitch the Oliver! You love your Orion installation now. You'll love it even more after you benefit from it on the road! 😎

Top kitchen cabinet above the microwave just behind the light switch panel. I reposted this picture taken by @Ronbrink when Ron installed his fridge vent fan. Lots of wires in there but not too many RED ones!

Cool, easy fix! Empty the kitchen cabinet and remove the access panel. You should find it easily but be careful not to disturb the other wires too much! 😎

jd, thanks for the pic,,..yep my center red wire is missing / not connected to the toggle switch and floating somewhere in the wall..... I have the use of my neighbor's scope, hopefully I can find the center red wire. Should be / could be a quick fix ...maybe? Few would take the time to pull the toggle switch and send me the pic You are the best !!!

Oh Man, Geoff has the knowledge and the tools, and since I did the prework, he will understand my post! 😎

OK, so forget the jumper and I'm hoping you have a multimeter. If not, get one ASAP! On the main switch, the one at the entrance, the center RED wire is 12V+. The two gray wires will carry 12V+ based on the position of this 3-way switch. When down as pictured the red is connected to the upper gray wire which carries power to the bedside switch. This allows the secondary switch to turn ON when activated. When the switch is turned ON, the center red wire is connected to the bottom gray wire which will turn the Courtesy Lights ON. Set the multimeter to the Continuity setting, which looks like a ground symbol. In this position, you can touch the two leads together and it will make a sound like an alarm. The main switch should show continuity between the middle 12V+ lead and the top lead when OFF, and show continuity between the middle lead and bottom lead when ON! RE the bedside switch you could just use a jumper or you could test for continuity in the up/ON position. I understand this is a lot and I can get on the phone with you tomorrow if you like. BTW, as you can see in this picture, not a spec of fiberglass dust and these spade terminals were so tight I had trouble pulling them back just a 1/16" to get the multimeter leads to connect to metal. If this is above your head, start looking in the basement for wires disconnected at the lights. Best wishes, my friend! JD

Taylor, I'll go out and look at mine... In the meantime the real expert here, he who turned his water pump 3-way switches into 4-ways to add another switch for the outdoor shower is our friend Geoff! Maybe @Snackchaser is online?!

You're welcome, @taylor.coyote. Everybody should have 1-2 of these in the Oliver toolbox. Once in a Class C, I could not get it to go into Drive from Park after starting the engine! I soon realized the brake light switch was not working. I made this jumper wire then to bypass the switch. It kept me until the next day, when I replaced the brake light switch in the Napa parking lot in Cortez Colorado! 😎

Would love indoor storage but only if it could be on our property. Not happening for reasons or cost and building codes! I'm not a cover guy, too much hassle and cover inside a building, really? Any dust will blow right off next time out or with a good rainfall! But to each their own... With our Oliver outdoors, the rooftop solar will return the batteries to full charge when not in use. When it's this hot, high 90s this week, we run the Chill Cube A/C 24x7 so I'll change the inverter setting to recharge once a week. Hull #113 has not been "in storage" the 3 years we've had her. Put a cover on the TV two summers ago, to keep the sun off, and the pack rats read it as an open invitation. I caught it just in time but could have lost the entire truck interior vs. just some HVAC vacuum lines and part of the dash cover. I'm never using a car cover again. I'll take a little sun fade over this and rub marks from wind. We had a Class-C before where the pack rats one winter built a nest in the intake trough of the Ford V-10. Chewed all the Bilstein shock boots too! So grateful they're too big to get into any of the small openings bottom of the Oliver. I'm looking at ours now and do so everyday! I'm always doing something. This week she's in the driveway behind the TV since we just got back home. Working on replacing the outdoor shower assembly and will add a drip edge on the streetside of the roof (and rear) to match the one on the curbside (we get drip marks everywhere else but soon will not! 😎 First pic is a rare cloudy day early June on our 3-year anniversary! Then after a light snow last winter. If she was back there today, the whole yard is foot high green grass form monsoon rains and not a drop inside the Oliver! She's had all the elements and always comes out just fine. All pics taken from a living room window. I did a bit of weed-whacking yesterday and more today!

According to their web site, they do still make a “Traveller” model. Funny thing - if you enter “Happier Camper” into the Google search page - first hit that comes up is “www.OliverTravelTrailers.com”. Apparently, someone at OTT marketing has some web savvy! 😂

I just saw one for the first time yesterday at Glacial Lake SP - had to look it up. Apparently, they don’t get much bigger than this one. Web site says they ARE double-wall fiberglass - but weigh way less. I haven’t talked to the owners yet, but curious how they like it.
