The recommended tongue weight is 10% of the total for the trailer. Try increasing it and see if that helps.
Your probably getting more coupling into the H3 because of the shorter wheelbase. The only solution is to trade it in on a H3T. :wink:
Love the pictures BTW.
Will Definately test this out a bit.
The main concern I have, is that we have cr@p laws regarding towing, vehicle capacity etc.
For instance:
The hummer can legally tow 2,200kg, but our law states that anything above 750kg needs to be braked (have own run in braking system, etc). Luckilly my trailer is rated for 750kg:thumbs: so at 10% that means I would have to put 75Kg (165pounds) on the towball
Secondly the allowable weight a vehicle is allowed to carry is GVM - GCM which gives the hummer a carrying capacity of about 521Kg(1150 pounds).
So filling the petrol tank reduses the carry capacity to:
480kg (1058 pounds) (lose about 40kg)
Adding me and 3 passangers reduces the carry capacity to:
100Kg (220 pounds) (Lose about 380Kg and this is a bit optimistic, as i weigh roughlt 130Kg myself :emb
Adding the trailer at 10% reduces the carry capacity to:
35Kg (77 pounds) (Lose about 75Kg or 10%)
So this leaves you with only 35Kg or 77 pounds for the coolerbox, camera's laptops, extra fual in jerry cans(the trailer only has 2 jerry cans fitted), gazebo. and don't forget all the add ons I have on the Hummer, ARB Bullbar, Winch, roofrack, 35" muddies. It's actually a huge problem the way our law works.
On my pickup I don't have this problem as the carry capacity is 1800Kg (3,300 pounds)
and usually load 6 x 20liter jerry cans giving me 200liter total diesel or 2,200km travelling (1367 miles) as most places only stock 500ppm diesel, and I prefer to use only 50ppm
