questions about electrical schematics in a bighorn trailer...

Hi, im the second owner of a 2011 bighorn 3055RL 5th wheel and have some questions.... we have had 2 different 5th wheel RV's over the past 35years, so we arent newbies to the RV world, but its always nice to learn more about the trailer I own...

first, what is the difference between the BigHorn and the BigHorn "Traveler" models?... ive tried to do my own research on it but cant find anything that tells me what the difference is..... so how does one know what model they own?

second, I went thru the HUG and HOM pages of the TOOLS, but cant find a wiring schematic for the bighorn trailers.... is there one available?.

what im wanting to do is add an onan generator and wire it in thru an automatic transfer switch (I have both newly installed and operational in the trailer, but NOT yet wired to the trailer system) and would like to find how the electrical circuit runs thru the trailer and where the best place would be to break and reconnect the shore power to the transfer switch....

I would like to see a schematic of how the shore power circuit runs thru the trailer, and how the other electrical (secondary) circuits are wired throughout the trailer.... a couple interior switches dont seem to do anything and I would like to know what they are wired to...

ANY help or hints for the bighorn trailer specifically would be welcomed by me... thank you

Hi centerline,

I don't think Heartland gives out electrical schematics. But we have quite a bit of information in our owner-written Electrical User Guide.

If you take down the rear wall of the pass through basement storage, you'll see the Power Converter (120V AC to 12V DC). The automatic transfer switch is typically mounted nearby. The main circuit breaker panel inside the trailer is a bit further back. If you go inside and remove the cover (with power disconnected from the trailer), you can then pull it into the coach a bit to work on it. The incoming shore power cord has 4 points of attachment (2 hot, 1 neutral, 1 ground). You'll probably want to move those connections to the shore power input of the transfer switch, and add a new section of AWG #6 4 wire between transfer switch output and circuit breaker panel inputs. The Generator also has 4 wires. The generator wires usually go to a junction box, and a new piece of #6 wire goes from the junction box to the generator input of the transfer switch.

If you bought a Progressive Dynamics PD52 transfer switch, the inside lid should have a wiring diagram that shows which wire goes where.

If you're not very certain of how to wire this up, you might do well to get some help. A mistake can create lethal hazards and can also cause significant damage to stuff in the trailer.

As for differences between Bighorn and Bighorn Traveler, if you have a 2011 it's irrelevant because the Traveler went into production several years later.

Thank you.... I have the electrical knowledge for RV's (and boats), but was asking the questions to minimize the my troubles and intrusion into the underbelly of the trailer to get things hooked up as they need to be.... i will check out the link you sent.. thanks again....
