BusBar Extreme Veteran Date registered: Apr 2006 Location: UK. North West / Wales Vehicle(s): 463 300GDL, 460 280GEL Posts: 382 | RE: Simple roof rack ideas suggestions Mike, I acquired the exact same roof rack as yours for our recent trip to Morocco. Despite all the advice against I decided not to use it and took a trailer instead. I'm just not a fan of any type of roof rack, pretty much for the reasons Harald quotes. One of the Defenders on our trip had an aluminum alloy roof rack. Not sure of the make but it was certainly designed for off road use. It failed catastrophically due to fractures and literally peeled back off the roof causing some nasty damage to the roof of the Defender. Pretty sure Thule have steel clamps but the bars maybe alloy?

Canada Vehicle(s): 1989 280GE Posts: 1347 | RE: Simple roof rack ideas suggestions Maxwell Smart - 3/11/2008 9:09 AM More than the standard Thule, it was about 450$, I like the look of the standard rack also, ( I have one on my VW) , however it is not load rated as high as the pro model. I plan on buying a roof tent and need the extra capacity. The bars are extruded aluminum and the legs are cast aluminum with steel clamps...no welds anywhere on the rack to crack or fail. I have had 6 sheets of plywood on it with no flexing at all. I think the G's gutter would fail before this rack snapped. However, there is a 3 bar (6 leg) version available, for those that want to really test the gutter....750lbs rating. elevatorbernie - 3/11/2008 7:30 AM If your going Thule use the 332, I have it and it's stronger (500 lbs with 4 feet and 2 bars) than the regular type Thule rack and feet. Also it can be use with the basket. :) I was wondering which Thule from the professional series fit... now I know. Though I do prefer the look of the standard Thule - the added strength of the pro series is a bonus. How does it compare in price? | ||

That in context of the dynamics and forces actinig between the moving car and the loaded rack that Harald wrote about. The highest ratings I heard of are for "professional" racks like Hannibal and African Outback, up to 200kg in Mercedes G version. The same rack on LR is rated at 150kg or so. Static ratings (car not moving) are meaningless and dangerous. What BusBar described was most likely an overloaded rack on a LR. It is easy to exceed "real" rack rating. A roof tent and 2 jerry cans can do the trick. | ||

Using some of your ideas and experiences along with some of mine, I think I can come up with some sort of "mini-Hannibal" type rack with large footing to rest on rail/gutter and stout enough to handle minimal load of fuel cans while transporting over washboard roads.

I agree it's easy to exceed the "real" rack rating, when all you get is a static rating with most racks. However with the Thule, it's a rack made for contractors moving material at working load rating of 500lbs max., (not static) that is recommended; car moving on flat paved roads not offroad of course. Common sense would say if one was offroading with 500lbs loaded on it, you might be asking trouble. Edited by elevatorbernie 3/13/2008 1:42 AM | ||

Seemingly the same rack mounted on a G should have a different rating (higher) than mounted on another car. Now if we differentiate what kind of roads (or no roads) the car is moving--that creates a further complication. Don't contractors enter construction sites that occasionally resemble offroad? | ||

Who knows how that affects the stress patterns in the material... It's an external roll cage which will pass through the roof and which is subsequently bolted to something solid. In a Defender that's a long way from the roof It's completely separate to the roof rack. Still can't figure out the make of the rack even if I zoom right in though. | ||

Mike I am in the brain storming stages of a couple rear bumper/swing out tire carrier/ gerry can holders for my G500 and 280GE, I will keep you updated on my progress, right now im looking for a hinge strong enough to take that load. I know its not the direction you are heading, but you might want to consider other options, this design is the best solution I have found. Id like to have both swing out arms easily removable for the city where a spare and extra fuel are slowing me down. Here is a quick sketch: note, blue is the hinge/ yellow is the latch Edited by chris505 3/15/2008 3:38 PM (Kanada14.1.JPG) Attachments ---------------- Kanada14.1.JPG (29KB - 3 downloads) | ||

I bent these to the profile of the roof, with a slight air space, using a gas torch. These are then clamped to the gutter rails using 4" angled clamps with 2 bolts. If you bend the clamps to 85 degrees and put a 5 degree bend on the top edge the bolts pull the rails tight. I've only ever had the roof tent up there (45Kg) and never had any trouble in 5 years.
Chris505 - if you mount off the bumper you will have to allow for body mount 'flex' in any upper fixings
Sorry for the poor photo, can take a close up tommorrow if it helps.

T.Schuhe Elite Veteran Date registered: Apr 2006 Location: Olympia, Washington State, USA Vehicle(s): 460 1985 LWB 300GD five speed Posts: 711 | RE: Simple roof rack ideas suggestions Thule is a wonderful product, and can withstand abuse. However, the two point per side approach is not sufficient when carrying loads over difficult roads. I have living proof of vehicle damage, not just the rail, when the two point system is overloaded. A second Thule (two kits, if you will) mounted as four cross bars, would make sense it you need to carry loads on the roof. This would act to spread out the load. Another line of thought is that if you have loads that heavy overhead, top-heavy driving methods and geo challenges need to be adjusted. I can describe many miles of having driven vehicles where each twist and turn increases the seat-pucker factor index to unacceptable levels. :ohno: Cheers! | ||

BTW those hanging jerrycans scare me... That's Dirk. Dirk has no computor so you wont meet him here but come to SA and we'll show him to you! Dirk will make a his old stock 300D with stock tyres go to places that makes baboons cry. He and Amzimmy keep their fuel like that - in fact all their heavy stuff as low as possible What scares me more is 250 kg of muck above your head on a coil sprung vehicle with softened tyres. I use a light aluminium roofrack with a 30kg tent on it only in "full battle kit" I remove it as soon as I can - It looks nice but just costs fuel (1km/liter extra) Mike - back to your original post - consider kidney tanks or a long belly tank on either side of the chassis (Jambo show us yours??). You sound priviledged to have space in your truck enough to dump the rack or do you need it for sundowners? | ||

Do you have a link or more info about the basket rack? I like it quite a bit, very low profile. | ||

I pulled the pic off of ebay-UK a few months ago because I liked both the G and the rack. You should be able to find more details on the rack in this catalogue: http://www.mercedes-benz.sk/pdf/accessories/brochure_access_g.pdf I currently have a Thule rack... not sure if it is OEM as part of a factory "ski rack" package or not, but I've decided it is useless unless carrying a kayak, surfboard, or something... it will soon be mothballed.
