Our F350 SRW tows our 310GK just fine. But it the most (heaviest) trailer I would want to tow with a SRW. I am at, but under the weight limits. I think you have to be careful in how you load the trailer. It is easy to get to much pin weight for a SRW (generators, extra batteries, washer/dryer, waste in the black and grey tanks, "stuff" in the front compartment and basement) all add up fast. We (wife and I) travel 4~6 weeks at a time and have no problem with weight, but we do not pack especially heavy. With the 310GK you can also get to little pin weight ( full fresh water tank and little else) and cause some unsettled (bouncing & buffeting) behavior.
We are in Colorado and I have pulled in some very high winds. The 310/SRW handles it fine (tip - SLOW DOWN in bad weather or pull over. Stop if you have to), but a dually would have been much more stable.
Weight wise, the 2020 (and later) F350 SRW with the long bed, crew cab and diesel got a significant bump in payload (11,500 to 12,400#). Since 2017 those specific trucks (gas too) have come with a 48 gallon fuel tank (very nice). A 310GK is the most (heaviest) trailer I would want to pull with a SRW. As Brian said above "The 310GK is the only Solitude I'd personally tow with an SRW truck. Anything heavier and I'd get an F-450." or a F350 DRW.
