Make mine root beer, and I'll join you. We may be heading down to Florida in November. That is still not certain though.

The math is pretty good in the limit as you approach zero and infinity is a perfectly good mathematical concept. It's just that calculators can't handle it. However, it's probably impossible to achieve zero considering it's a three dimensional distance and you also have to consider the tire/road interface which will introduce slippage as forces increase. All that said, simply invert the fraction and drive it to zero. Same result and same guidance. Minimize ball to rear axle distance, maximize TV wheelbase, sat down, have a Bud, and Camp On |

Had the chance to talk to several people with the new Dodge 1500 Eco diesel. The best one had driven from Texas to Oregon towing a trailer that showed just over 2900 pounds axle weight on a set of scales. He said he cruised at highway speeds, had come over thru Montana and his trip MPG had been running near 20. Most of the others reported about the same and doing over 27 running empty. (One with a heavy trailer reported about 14 mpg.)
Just something to look into and think about. |

Thanks. This is good information to know. The math does not quite work as if there is a 0 distance, it would generate a "divide by 0" error. However, the point is clear that closer the result is to the wheelbase, the better.

The operative factor here is the ratio of vehicle wheelbase divided by hitch ball distance to the rear axle. If D is the distance from the ball to the rear axle, this ratio is WB/D. The larger this ratio the less steering by the trailer and the less sway. As D approaches zero the ratio gets very large like on a fifth wheel or tractor/trailer rig.

Now that you mention it - I noticed a little sway when I put a longer stinger on the ball so I could open the tailgate. I hadn't noticed it before, but then the trailer was fairly new then. I still plan to put an Andersen hitch on this winter.

That is what I was saying also. For my Escape, the distance between the rear axle and the tow ball is about 3'. On larger vehicles, that distance might be more than twice the distance with the corresponding increase in leverage. That is why I feel quite safe and why I have not experienced any significant sway over about 10,000 miles of towing with the Escape. I feel a gentle nudge when passed by tractor trailers, but nothing significant. For me, it is a good thing to feel it as I had a stroke which took away part of my peripheral vision on the left. The nudge lets me know something is there and to check my mirrors again. |

Your observation brings up a good point. While overall wheelbase is important, the distance between tow ball and tow vehicle real wheels is a factor. The smaller distance tow ball to TV rear wheels the less leverage the trailer has to induce sway. Some of the SUVs have the rear wheels set relatively far back toward the tow ball, which is a good thing.

I like to review these guys. They have many posts, on YouTube, on numerous TVs.
