I just read this thread and saw the comment about hitch extension. Be careful, as adding distance between the hitch ball and the truck's rear axle
gives the trailer *more* leverage and more effect (both bounce and sway) on the truck.
OTOH, *shortening* the hitch bar will reduce the effects. Last summer, I pulled the pin on my hitch bar, pushed it into the receiver as far as it would go and drilled a new set of holes -- made quite a bit of difference even tho I only shortened it by a few inches. Recently, I modified my receiver to move it further forward and up a few inches each on my truck; the effect was even better but not as noticiable as the first shortening.
Another way to attack the effect of balance on the truck would be to *lengthen* the tongue of the trailer by attaching a longer arm with coupler underneath the original one. I have seen a 13 Scamp
with a tongue long enuf to have a bike rack between trailer and truck and have plenty of turn room; the owner constucted a "T" and welded it to the A-frame underneath.
BTW, lengthening the tongue will have the effect of lightening the tongue weight
as the torque lever between trailer axle
and coupler will be longer. Anyone contemplating carrying more load on the tongue (genset, extra propane
, bikes, etc) could benefit from this.
