Hi Copilot,
Congratulations on your Bighorn and welcome to the Heartland Owners Forum. You'll find lots of useful information here along with a lot of friendly people who are always ready to lend a hand and share what they've learned.
I think you'll want to consider a couple of things:
- Weight on the wheels and tires: it's never evenly distributed and it's not unusual for the rear Off-Door-Side (ODS) wheel to be running much closer to the weight limit than the others, especially if there's a large slideout on the ODS, with kitchen appliances. Our Landmark Rushmore, which has the rear entertainment center, and the large kitchen/living room slide on the ODS is very close to the weight limit on that wheel/tire, even though our overall weight is 15,000 vs GVWR of 16,200. I'd lighten our load on that wheel if I could.
- Towing capacity: you didn't mention what tow vehicle you've got. If you're near the tow capacity you might want to think twice.
- Payload: everything you put in the trailer adds to the vertical load on the back of the tow vehicle. Depending on what options you have, how you're loaded up, and what the tow vehicle payload is, you might want to save weight.
On the other hand, what's a few pounds between friends? If the trailer handles well while towing, enjoy life.
