    Next I had to start testing the Hummers offroad prowess

    Decided to visit my local "De Wildt" offroad track just to start with the mild stuff.

    and as you would have it, I had a breakdown en ruite to the destination

    Was driving up a hill when the hummer just started loosing gears, just slipping, but at least I had first to get to the closest petrol station.

    So I called the GM assist and they send out a towtruck to my location.

    Tow truck got lost and took 3 hours to reach me.

    the verdict after GM's inspection was that the tranny cooler had a leak, getting radiator water into the gearbox and stuffing everything up. Got repaired under warrenty but I only found out later that they were supposed to do an external oil cooler when they do the repair (so I have this on my to do list now)

    Next up was the camping test

    hooked up my offroad tailer, and headed for the Hartebeespoort dam for a fun weekend

    The hummer feels a bit "soft" when towing, as any movement/sway the trailer gets transmitted to the hummer, but I think its due to the soft suspension package of the H3 Adventure (might be something to look into)

    Nice trailer.

    Thanks, the trailer works like a dream

    I keep the tongue weight between 10 and 50kg's (22.5 - 110lb's) as I usualy do the hitching by myself I don't like to work that hard to get it hooked up

    Edit:
    When towing the Trailer with my daily driver pickup, I don't have this issue, thats why I'm thinking it might be the softer suspension

    My first mod on the Hummer would be some Muddies

    after some research the Kumho KL71's seemed like the best way to go, unfortunately the biggest they stocked this side was 33"

    after phoning the importers and explaining to them that the Kl71 indeed is manufactured in a 315/75/16 size I got them ordered and installed

    Got them just before X-mas, so it was a present for the H3

    I then went ahead and started cranking the torsion bars to get the hummer more level, and instead of looking at the hight gain, I looked at the CV angles, and stopped once they became too angled for my taste, final hight from centre of hub to fender is 595mm or 23.4Inches, and afterwards I read on the hummer forum the max is 23.5 Inches

    The drive of 700km (434miles) felt weird, but I put it down to the larger muddy the Hummer was sporting. This was untill I filleld up in Kuruman and checked the tire pressure it was at 3.6 Bar (52 Psi)!!!! and I instructed the fitment centre not to exceed 2.2 Bar (31 Psi). Mind You I did get 8km/liter (18.82).

    Another thing I noticed whas the constant shifting of the auto box (our highway speed limit is 120km/h or 74.5Mph with a 10km/grace margin, so you can do 130Km/h or 80Mph). so guess what my next mod was going to be to get the shifting sorted .....

    hehe, I'm a photo horder, lol

    So the next mod was the PCM for less flash, took 5 weeks to reach my hands with our fast postal service .

    and what a difference the PCM flash made. the hummer pulled stronger, shifted better, and golly the offroading felt improved, suddenly I could say traction control was working

    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.

    Love the pictures BTW.

    Did some more trails with the hummer, and then it was the rainy season....

    "Photo updated"

    Decided it was time for a Snorkel (think this was more of a cosmetic thing, than of a protection thing, as the electronics location will prevent me from trying to do deep wadings)

    Obviously Safari snorked doesn't have a Snorkel for the 2007, so I got a 2008 one, and had it fitted at a offroad specialist

    This littel piece that came with the snorkel was discarded, as it doesn't mount on the stock 2007 airbox

    A fitting was made to fit over the existing airbox inlet pipe (But after reading another post I will be doing some adjustments here later to improve the airflow thru this little pipe)

    And the end result

    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 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 )

    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
