Regarding tunes - I have to admit, I don't understand it at all. Besides that you need a reputable person doing it. What does it improve? Pulling power? Speed? Both are not my issue.
My main issue is pin weight on the horse trailer - 3 horse slant with living quarters. Bought it used, have a large 5th-wheel, and no issue with pin weight there. But I found out, goosnecks are leveled differently...Just got Sumo Springs today (SuperSprings;front and rear) today. Looking into tire upgrade next.
Does anybody know what the rear axle and bearings can actually carry (besides the sticker weight)?
Thanks Sabine
