snowmobile trailer tounge help advice needed,

[MikeD74T]

I've modified things that worked well & some that didn't. In this case I'd fab a completely new tongue from steel ( because I also can't weld aluminum)with all welded joints. If it works - great, if it don't just put the original tongue back and restore the trailers original value. By making a new tongue you gain in another way. You can make it longer which should reduce sway some as well. I'd be wondering whether a connection bolted to the original tongue will get you where you want to be strength/rigidity wise.
Something else that may help is a method to keep the 4 wheelers loaded at exactly the same place once you determine where the sweet spot is. i.e. a fixed length chain & hook or strap/bar at front or back & tensioner at the other. This also simplifies loading. MikeD74T

I would go with MikeD74T idea and go with a steel tongue and a $60 set of air shocks that you can adjust to your needs

what kind of jeep?

TJ's dont tow more than about 1500 lbs total without issues.

Load via toung weight.

you should have ~10% of your total trailer load in toung weight.

so 4000lbs of trailer and 2 ATV's would mean 400lbs toung weight.

load your ATV's, disconnect from the vehical and do this

Tongue Weight Scale

once you have the proper toung weight, mark the postions of the ATV's and reconnect to the tow veihcal and see how it sits.

If i had to guess, your exceeding the tounge weight capacity of your tow vehical to properly tow that setup.

in which case a load leveling hitch is not the answer.

I'll add 2 cents worth. Watch out using stainless hardware on anything structural. Theye are generally about a grade 2 bolt..... very weak.

Ditto to Ductape....It will probably be the aluminium that corrodes to the point of failure. Back when Jeep made pick-up trucks they used aluminium bumpers- for a while. My dads bumper bolts finally pulled right thru the corroded bumper. I once made a longer tongue for a camper trailer out of 4" aluminium electrical conduit, clamped between two pieces of channel iron. Worked great but only got used in the summer when we had no salt to contend with.... Love those longer tongues.
Most ski-doo trailers aren't built to haul ATVs with their load concentrated at the 4 corners instead of spread out over the whole track and skis

HI GUYS,
YOU have convinced me to just use my tandem,it aint worth the effort to modify it.My oldest daughter is about ready to have her own so ill need the tandem any how to haul 3.In a couple years my other daughter will be riding too,ill be hauling 4.Time to park my CHEROKEE and make up my mind on a truck. 4 atvs is about what my tractor weighs,but i aint gonna haul them 700 miles with my jeep.I TOOK 3 last year without any problem,but i think a truck would fit the job better.
You gotta laugh at this:The last time we went and the trailer got a little wobbly ,it scared the old lady I told her we really needed to step up to the plate and buy that new TUNDRA now,before we wrecked She said nice try,but not yet dear
THANKS FOR THE INPUT ALL.
