Wow! Can't believe they put all that on a single axle. I just watched a walk though and it shows to also have a slide out. You got a good spot.
Words of advice on a heavy single axle trailer. We owned a 17 foot Casita Spirit Travel trailer before going to the Forest River NOBO 19.1 which is twin axle.
The Casita 17ft was 1700 lbs on a single torsion axle. In the first few years we blew out every tire, one tire per trips, long trips from Houston to New Mexico \ Colorado Rockies. The Class C Good Year Trailer tires just couldn't handle the weight and we do carry everything but the kitchen sink.
So if you get a blowout on the new tires, within the first couple years you are exceeding the tire load rating. We stopped the blowout by moving to Class E tires, and those were the Michelin E tires, the same tires UHAUL uses on their trailers, and they were WAY BETTER. You could tell right away, the shimmying down the road stopped, and they felt smoother. Didn't have another blowout for 10 years after that and sold the trailer with those same tires on it still looking good. They resemble 18 wheeler tires and are 8 ply side walls and I think 10 ply main tread. I would just do that if you start having issues, do it right away, and don't wait for the 2nd or 3rd blowouts like we did because when these tires blowout, they can take out the side of the trailer and the wheel well as well. If you have C class right now on them and I do not know, and they are new, consider selling them on Craigslist and go straight to the E rating.
