    Had an MOT yesterday and after taking everything out of the van the previous day, I happened to ask the garage did their equipment weigh the van they said that their breaktesting machne did.
    As a matter of interest I asked for the weight and remember the van has been plated to 3850.
    They cam back and said that it was 3700 :eek:
    Thats with a full tank of LPG 1/2 a tank of diesel 1/2 fresh water. and nthing else...

    Thats a worry,150kg for fuel and everything else..

    Plan of action...
    Off to get the van weighed on Monday then decide what to do.

    Questions..
    How do I work out the axle weights? Is that on the existig plate?
    How hard is it to increase the plate weight? Simple form filling?
    Will I need to change the suspension/tyres etc.

    Wish I never asked now...

    There is very little that can be removed from the van and adding two funsters will reduce the spare payload .

    Suggestions sensible ones please..

    Oh yes the original spec for the van suggested that the unladen weight was 3100 goodness nows where the 600kg has appeared from? The only mods are sat dish, Galsow 11kg x2, two solar panels. )



    Just seen this on another forum
    "Just had my Rapido 786F weighed, fully loaded with a 13kg and 6 kg gas bottles, 90% water, full fuel tank etc.
    gross weight 3400kg
    front axle 1500kg
    rear axle 1900kg "

    I am really confused now,

    You don't know how accurate their machine is. A trip to a real weigh bridge is probably in order. Try and find one that can weigh each axle individually as well weighing the van.

    Your questions:

    The axle weights are on the plate. Yours will probably be 1850 front and 2000 rear

    Depending on what chassis you have you might not be able to increase it any further. 3850kg is the upper limit for a lot of them.

    Air suspension and tyres will probably get you more on the rear axle but not necessarily increase the maximum total weight.


    If you get it weighed properly and confirm that weight a phone call to SVTech needs to be your next step. They will be able to tell you your options.

    Yes, I know there are others and SV are expensive and all of that. I'm not interested in that debate again. What they do have is the breadth of knowledge of motorhomes to be able to give you your options straight away over the phone without having to research it.
    If they tell you that you could go to whatever weight use whoever you like to actually do the exercise.

    Sounds a little like our Rapido 791 FF, even when I had bigger tyres and air suspension fitted and uprated to 3850 Kg all I could put legally in the huge garage was 40 Kg.

    in truth most really need m,homes with 6.5 ton or even 7.5ton . gvw.
    m,homes built to 3 ton gvw etc are really only weekend or day vans .

    The plated gross weight will be less than the total of the maximum individual axle loads, in order to allow for uneven loading.

    In that case you will find it very difficult to use all of the GVW without overloading one or other of the axles. Usually it will be the rear!

    I wouldn't try and run it right on the limit and I'd be concerned if it was.

    If it was actually running at 3850 it would, IMO, need to be plated higher than that.

    Anyway if I needed to I can get the rear uprated by a further 200kg. (y)

    At the last MOT on our 7500kg RV, I asked if he would note the axle weights during the brake test.

    He swore the tester had just been calibrated

    Rear axle....a little over 2000kg :ROFLMAO:
    Front axle ...640kg :eek:

    The front mounted V10 engine weighs more than that and the four rear wheels alone total 200kg :LOL:

    That depends on the van
    I'm allowed 2100 front but cannot go over it unless I deliberately add weights(we are under 2000 fully laden)
    I'm 2400 rear but cannot go near it without breaking 4250 gross.
    Any extra weight is required at the back so uprating to 4500kg is a no brainer allowing me to use the full 2400

    When did you last have a damp check? Is it possible you are carrying around an unknown quantity of unusable water? I hope not for your sake. Allowing 100 kgs for your extras that makes the overweight about half a ton subject to the accuracy of the scales or about 20% overweight!

    For a start you don't say what chassis and size tyres you have, that will give a good guide to see if you can uprate.
    As you are already plated to 3850kg it is unlightly you will be able to increase this if you are on the light chassis but there is a very slim chance your van is on a 4250kg chassis that has been down plated as I said very slim chance.

    As others have said before you do anything talk to SV Tech, I jumped the gun on mine and fitted wider tyres with a higher load index to take the real axle increase, then I spoke to SV Tech and found out that the Al-Ko AMC chassis is limited to 2000kg on the rear although it can be increased by fitting air assist which is expensive for an Al-Ko chassis.

    Yes air assist for our Alko 4250kg maxi chassis is £1600 + VAT fully fitted don't know if that will give me increased GVW though as we don't need to uprate.

    in truth only a fool would buy a m,home with only 400kg payload with that many berths and seats .
    it should be unlawful to sell one like that as well.

    As the van is plated at 3850 I reckon a previous owner must have had it uprated.
