did my first real trailer trip this past weekend and was generally ple=
ased but=20
found several things I need to address.  I can't seem to find the info=
 I'm=20
looking for easily.

first... the rig is
2008 Suburban 5.3 L  4 speed auto  with 3.73 axle and=20
20" tires
towing package installed stock from factory
GCWR is rated at 13,000   (from the manual)
Stated max trailer weight is 7,000 (from manual)

trailer is a 18' Anderson car hauler  weighing 2,400
Load is a 53 F-100 weighing 3,840  with the engine end ahead
of the first axle...  (truck front end weight is 2300 per the county s=
cales)
total trailer load 6,240

I did the bathroom scale tongue weight thingy and got

575 # without my wife's mobility scooter mounted in front off the truc=
k
715 #  WITH                 "=20
                          "                    "                      =
    "

I think I'm within acceptable tongue weight range either way.   But de=
fer to wiser minds

I have a manual tongue jack that's tired and want to switch to electri=
c (for ease and to sake of my shoulders  brand recommendations ??

also  how is the rating of the jacks calculated... is it just the tong=
ue weight or do I need to calculate some part of the load ahead of the=
 axle too?

I-59, I-24, I-75, I-40  is a collection of bad paving, dips, humps, po=
tholes that resemble shallow wells  and made driving a puckering exper=
ience
especially for a trailering noob.  Kept my speed under 60 mph and on g=
ood roads it was fine but as the condition of roads deteriorated I exp=
erienced
a little wander and fishtailing that I could correct but in metro traf=
fic it increased pucker factor by 50-70%

Add that to the lookey-lous that want to eyeball my truck as they drif=
t over closer than they should... and it seemed like NASCAR rubbin is =
racing time.

Love to hear recommendations on  electric jack ratings , and other wis=
e advise to make next trip more safe and enjoyable..  I know you guys =
have a
well spring of knowledge you can pour over me.

thanks
John

Regarding the "wandering and fishtailing": my first thought was that too
light tongue weight will cause that, but it sounds like yours is heavy
enough. A weight distributing hitch will help a lot.

Finally, you indicated you're new to trailer towing - raising the
possibility of the driver over correcting. This is what flyers would call
pilot-induced-ocillation. This tends to go away with experience, especially
if you tow regularly.

Howdy,

I don't know anything about electric trailer jack ratings, but I would
assume the load it sees would be a bit less than the actual load at the
trailer ball, since its closer to the wheels/pivot point of the trailer.

I've always heard 10% as the absolute minimum for tongue weight.  If you
were getting sway, I'd move the load forward a bit regardless to see if
that helped.

A friction sway control is super cheap... $30 for one at Horrible Freight.
No question I'd add one as insurance.

Mark
