I purchased the Lippert 1.25 inch receiver hitch for my 2016 Bighorn 3685 and had it welded onto my frame (see pics). Locking to replace it with a beefier or more stout 2 inch receiver that will not have as much vertical movement. I will use it to carry two bikes that each weigh 55 pounds...

Thank you David and Bill - you guys were exactly right. I used an electrical detector (sniffer) to track the power. The inverter was getting power in and out of the switch, but shore power was only going in - not out. That's why my fridge would lose power when connected to my house. So I...

Thank you David - any chance you know where the transfer switch is located, or have a picture of the electrical board in the trailer garage?

So in my 2016 Bighorn 3685 the fridge used to work any time shore power was plugged in. Now yesterday the fridge sopped working while plugged in to 50 amp shore power. Checked breakers, fuses, all good. The plug was secure in the outlet. Looked at the inverter and found the test button out -...

Where is the Progressive located in your trailer? Not sure if I ever located where mine is.

Any problems with the AGM batteries since you upgraded to them? I have the Magnum pure sine wave inverter too. What about charging the AGM batteries? I have a Progressive Dynamics PD9200 Series power converter with a built-in Charge Wizard. Would that be safe for AGM batteries?

Hello all - I have a 2016 Bighorn 3685 with a residential fridge. The last two trips found me arriving at the campground with the freezer and fridge temperatures significantly higher (43, 38) than normal. The inverter appears to be working normally. It turns on (green light on inside trailer)...

As I was winterizing my 2016 Bighorn 3685 yesterday I noticed that one of my red running light lenses on the upper aft end cap was missing. Only the exposed led remained. Does any one know where to go to order a replacement lens and retaining trim? In the past I went through Camping World...

Hi everyone, new to the forum and new to Bighorn. Our 2016 3685 has a new style vent high on the side just outside where the microwave and range fan are located. I cannot figure out how to open it! Some posts read push the two tabs in, others say pull out. Can somebody give the definitive...
