We've got maybe 700 miles towing now. The first 200-250 miles were with my B&W Companion. The last 500-ish miles were with the Andersen. We haven't deal with big hills/mountains at all and haven't noticed any issues with towing. The brakes on this thing are WAY better than my old rig (2013 Sabre 36QBOK).
I just weighed the Spartan 1245 yesterday. Fresh water tank was probably 2/3 or more full (let's say 70 of 100 gallons). The fill inlet is behind the axles but I'm not sure where the actual tank is. We don't carry toys as the garage is the kids' room- but we do have the garage filled (sofa bed, a ****-ton of furniture and household items, and the washer/dryer combo); I wouldn't be surprised if it had 1,000+ lbs.
Overall weight was right at 21,000 lbs.
Pin weight was 3,260 lbs.
Pin weight percentage was 15.5%.Looking at the specs, the dry weight is 15,051 lbs. with a dry pin weight of 2,627 lbs. for a percentage of 17.4%.
Honestly, I'm surprised at how low the dry percentage is given that the pin weight is almost definitely going to be unloaded with a toy hauler. I always just assumed the specs were wrong and that I'd be looking at a significantly different pin weight.
Apparently the specs were right and the pin weight is super low.
No issues in the limited towing, though. I have another 1,500 miles over the next 2 months to see what comes of it.
