I tow with a Ram 3500 SRW. I have tires that are 2" taller than stock, that lift the truck about 1". My actual measured tongue weight is 570 lbs. I use a 3" drop hitch and it is perfect. This allows for an approximately 1 1/2" sag when connecting. I probably have about 800 lbs of total gear, tools, etc, in the bed of the truck when traveling. Ollie rides as close to level as possible set up like this, and the truck is slightly down in the back from the weight of the gear and the tongue weight combined.
It also seems like too many people buy the Anderson hitch out of fear, rather than because they actually have reason to think they need it. Remember, Oliver trailers are extremely stable. I have an Anderson hitch that came with my Oliver and I have never put it on. It has never been even slightly needed. Of course, nobody is qualified to tell someone else that they don't need a piece of safety gear. But, does it make sense to buy out of fear? Or with no data suggesting you really need it? Or to buy it for sway, when all you need is weight distributing?
If you want to tow your LE2 with a Corolla, you'll need it. If you want to tow your LE2 with a deuce and a half military truck, you won't need it. How about a 1 ton Ram? No. How about a Ranger? Yes. Where exactly is the line? Do you want one so that a lawyer can't possibly sue you? Good luck with that. We have friends that have towed their LE2 all over the country with an F-150, with no WDH. Not the slightest problem ever. Even though Ford says they need one with a tongue weight over 500 lbs. Anderson hitches have been known to cause problems with Ford stability control systems. In that situation, Anderson recommended turning off the Ford stability control system in the truck! Yikes! Never do that! So, if you don't need it for stability, and it can cause instability when installed, and you're afraid to go without it, and Ford says you need one, but the truck drives fine without it, and Olivers are known for their inherent stability, what do you do? And how can anyone tell you what to do? My solution was to not use one, even though an Anderson came with my Ollie. Your mileage may vary. Objects in mirror are closer than they appear.
