    Hi All

    I have looked around the forum but haven't been able to find an answer. I have been looking at Fiat Ducato van conversions and I notice that a lot of them are built on the 3300Kg chassis rather than the 3500Kg chassis. What is not clear to me is why the 3500 is not used, as it gives another 200Kg loading, especially as payload is a key factor. I have been advised that the 3300 should be sufficient, but if not, the upgrade to 3500 is only a paper exercise (at a cost I expect).

    My question is why is the 3500 not used more? Am I missing something, or is there a reason, if so what is it/are they? Is there some implication to Road Fund Licence, speed limits, insurance, or something else, or is it purely down to the initial cost of the base van?

    Cheers

    Trevor

    May used be based on the year of production you are looking at..
    Example my apache 700 has been based on 3850kg because that was the chassis at the time, then some came out at 4005kg and now latest is 4250...
    If the van is compliant at 3500 then yes you can upgrade it, few topics on here about that..

    Many are built on an ALKO chassis, not Fiat, Peugot or Citroen's own. (Basically the same vehicle)

    Chaps Trevor has asked about panel vans. Why complicate it by bringing in alko chassis!lol. Yet to see aa panel van on one:)

    3500's normally on longer 636 chassis. So you get more room and easy upgrade to 4250 as most on Maxi chassis.

    Have had 3300 as well on a 6 metre van. And that was fine as well. Depends what your looking at? We only buy European vans

    Its over 3500 that restrictions begin

    I believe that many motorhomes are built DOWN to a weight, so that the eventual 3.500kg can be achieved, as there are several factors that come into play over that weight.
    My van is usually marketed in Germany at 3.5 but on request the same van was plated by the manufacturers at 3.8.

    Be very carefully as some vans weigh 3300kg and max out @ 3500kg as did ours but the previous owner had it re-rated @ 3750kg.

    Easiest way to find out is ring SVTech with the chassis number for free advice on what is possible.

    Thanks all, but as Judgemental noticed, definitely a panel van, so no alko chassis ;)

    Why I am querying is that I have a deposit on a new van conversion which is rated at 3300Kg, but there is an optional upgrade to 3500Kg. What isn't clear to me is if the van can be had with the 3500Kg (ie extra 200Kg payload) why isn't it used? What are the reasons for not using this rather than the 3300Kg?

    I am aware of the over 3500Kg restrictions and want to stay away from them :)

    Cheers

    what van..tell us and may be able to help re practicability.

    payload is not the end of the story. as axle capacity can be reached long before max payload..so 3500 may be illusory in some cases...

    If its a UK van make sure you weigh it before buying..

    you need to look at the in running order weight and subtract it from the gross weight to see how much payload you have
    there are two chassis on the fiats the normal one and the maxi the maxi can go up to over 4 tonnes the smaller i think is limited to 3.5 tonnes and is obviously cheaper to buy as a base
    as a guide my conversion weighed in at 2.8 tonnes without the gas tank and the awning and with no fluids on board so at a guess im normally running around 3.1 with us both in it

    there is a "Light" as well, can run at 3300 or 3500. but rear axle only 2000 whereas Maxi 2400 - this impossible to overload in a PVC. but as I said earlier this don't mean you cant reach the max payload!

    Thanks Judgemental & Mitzimad

    The van is a Carthago Malibu 600 DB2 built on the light chassis. The quoted weight is 2824Kg, which with the 3300Kg chassis would leave a payload of 476Kg. One of the options is an upgrade to 3500Kg, which would then give a payload of 676Kg. Most of the time, the van would only have two of us in it, therefore the 3300Kg should be fine. I can see that there would be some occasions where there would be four in the van when the extra payload would help.

    What I am trying to clarify is why this uprated chassis option is not used more often as I hear a lot of people having insufficient payload and need to uprate the chassis (something I would rather address in the beginning if I can). I would also like to clarify what downsides there are of having the uprated chassis (apart from the initial cost). I haven't seen any as yet, hence my questioning the knowledgeable collective

    Cheers

    Trevor

    There is no advantage to using a 3300KG chassis as a base other than initial cost, yes it can be upgraded but that's at your cost not the converter's. 3300KG base vehicle is a joke for a modern camper conversion and unless many corners are cut regarding insulation and equipment levels it will be difficult to achieve a realistically useable payload.

    i dont think they should be using the light chassis at all even when uprated to 3.5 it will not have the extra heavyweight axles and brakes of the maxi chassis i had to search for a long time to find a maxi with low milage when i decided to build

    Out of interst, have you any idea what it would cost to get the higher rated 3500kg chassis? Assuming it is a different chassis from the 3300kg one it would be interesting to know how much they're trying to 'sting' you for when most PVCs are built on the 3500kg chassis.

    chassis is not realy the right term as were talking about pvc's its more the spec of tyres brakes suspension which are heavier on the maxi not sure if theres any extra metal in the floorpans as ive never seen two close enough together to compare maybe dave newell can enlighten me on this

    I don't think the 3500kg is necessarily a maxi chassis as our previous Autocruise Accent PVC was rated at 3500kg but wasn't a maxi.

    You do not have to worry about the PVC being overloaded as there is not enough room to put any heavy bits in there anyway, apart from some owners and there partners that is.

    Indeed.
    Many coach builts etc. are on Alko chassis, as is mine.
    Didn't read the OP properly.
