Itsy bitsy teenie weenie payloads

[Lenny HB]

I wouldn't go by online calculators either as they're designed to protect a coachbuilders liability. Auto Trail advertise the F70 as having a 500KG payload, nope, ours came factory fresh with 604KG with 2 x 6kg gas bottles added. With all of the factory cost options it has a 510KG payload.

Have you actually weighed it?

Hi we have an autotrail imala 730 with 330kg payload if I take off 70 for wife and 25 for awning 20 for solar panel 40 for clothes and 40 for bits that you need we are left with 135kg no water as I don't run with full tanks, so just cooking and kitchen bits so how much more do you need or should we be looking at upgrading the van.

Firstly what does your Mass in Service say? That's on all British built motorhomes and is definitive & legal, just add gas to that and what remains is your payload. Bear in mind that if your solar was factory fitted that's included in the Mass in Service too.

A dealer fit wind out awning on the 730 will weigh around 32KG, a dealer fit solar panel and peripherals will weigh around 5KG.
I weigh 138KG but a full locker of clothing for me weighs 15kg including a couple of big biffa towels, missus clothing weighs 9KG.

Maybe do a bit of recalculating?

Ha… at least most of you guys can work something out! I have a 31 yr old Hymer B644. My plate in engine bay says it is 3100 gvw, V5 document says it is 3400kg gvw and the original Hymer literature that I still have says it should be 3500kg gvw with the ‘as built’ configuration.
Help!!! From what I can see from the vehicle information my Hymer doesn’t seem to actually exist

 

[Jonno1103]

Waiting for delivery of new Bailey Adamo 75 4DL which has 390kg payload after allowing for drivers 75kg, 3/4 water and 3/4 fuel and 1 x 11kg gas so pretty useless by the time awning 30kg, passenger (weight not disclosed), tools, fire extinguisher, tv, pots, pans, plates, cutlery etc.
So I'm going to uprate via SV probably - what surprised me talking to the dealer today is that the 3.5 can be uprated to 4.25 as a paper uprate without fiddling with the suspension BECAUSE thats how they start life in the factory before the manufacturers downrate to sell to the non C1 buyers. Isnt it more sensible to leave at higher weight and then for the dealers to downrate for a specific buyer on purchase. Too sensible perhaps?

I thought the payload on the 75 4DL was 340KG?

If the V5 says 3400 that is the max you can run at keeping within the axle limits of the plate under the bonnet.

Yep, straight from the dealership onto a weighbridge at Amey Highways Dept, weighed 2901KG with the 3.5m awning fitted.

 

[The Wino]

I am of the understanding that if you’re stopped and weighed and you have a couple of empty passenger seats or an empty fuel tank, then the old bill will add 75kg per empty seat and a weight allowance to take your fuel tank to full. This is added to your weight and that decides if you’re over or not.

For example I weighed my van last week. Was 3140kg with minimal food and clothes, only me on board, full tank of fuel… MAM is 3500kg, so no problem… but it’s a 6berth. So 5x75=375kg added to 3140kg=3515kg. So technically at 3140kg I was over weight by 15kg.

Is this understanding correct. I was told this on good authority so I do believe it and it does unfortunately kinda make sense.

That sounds like a story down the pub to me. I think if you were stopped with 4 in and tried to sneak some off before you were weighed that would most likely happen.

Autosleeper Coachbuilts on a Merc chassis with manual gears:

All figures are calculated @ 3.5T but this can be raised to an MTPLM of 3,880kg:

1. Burford Duo: 117kg, (2kg).

2. Burford: 47kg, (minus 68kg).

3. Winchcombe: 262kg, (147kg).

4. Malvern: 279kg, (164kg).

Notes:

a. Includes a 75kg driver, 90% fuel and all tanks drained.
b. The payload figure in brackets becomes applicable once the Premium pack/Auto is added (7G Auto, Awning, Alloy wheels, spare wheel and carrier, 80w solar panel, cab AC, upgraded stereo etc, circa 115kg.
c. If you opt for a 3rd and 4th travel seat on any of the above named variants then this will reduce the payload by a further 60kg per van (estimated).

Looking at the AS website these all have a MTPLM of 4100kg.

 

[cyberyacht]

No, that's the sum of the axles. MPTLM is 3500 plus 1000Kg for a trailer, so your TOAD will have to be a lightweight. Only 500KG payload over the MIRO as well.

Dealer quoted 390

I would check that with SV Tech. This is the Ford vin plate from a new Swift Voyager 584 which uses the same chassis as the Adamo.

View attachment 694755

The combined weight allowed on the axles is 4100 which is the most the MAM can be. The train weight would remain at 4250 which give only 100kg of towing capacity. Therefore no fitting of towbar!

This is the reulting Vin plate from swift after conversion.

No train weight allowance. When I spoke to a dealer at the Shepton Show he said that they would have to get a new COC from the converter to uprate the weights.

I have the forms from SV to complete but until I take delivery can't get pictures of the van plates - but yes, SV are the experts. Dealer said 4250 which surprised me. Bailey FB group quoted 4000 on a paper transaction without air suspension.
Not planning on towing so won't need a tow bar anyway

It's 4100KG as both the Voyager & Adamo are built on the L3 chassis plus the longer Adamo's are now fitted with an AL-KO extension.

Same with the AT F Lines, SV Tech do them as a paper exercise to 4100KG too but as their 7m+ vans are built on the L4 chassis they maintain a 500KG towing cap' - lowered from a standard 1000kg.

 

[Fdhadi]

I blame the Weigh-bridges
Surely all these converters don’t make mistakes.

Mines a 7.5

Yep, ours is about 7.4 but doesn't have the AL-KO as the chassis is the L4 and has a 1000kg tow weight.

Bailey opted to keep the L3 and add the AL-KO in order to give their Adamo's a towing option, the older one's don't have this. Problem is that the L3 + AL-KO is heavier than the L4.

Don't suppose anyone knows the payload of a 2002 hymer b574 .

Don't suppose anyone knows the payload of a 2002 hymer b574 .

The only way to be sure is to take it to a weigh bridge and then deduct the actual weight from the revenue weight shown on the V5C. Whatever the original payload was supposed to be probably bears little resemblance to the current payload.

 

[Ridgeway]

My guess is most optional items will add up to a couple of hundred KGs easily.

Bike rack 20kgs
Awning 30kgs
Aircon 30kgs
Extra battery 40kgs
Etc etc

Amazing how quickly it all adds up

 

[Towat101]

If i load up with diesel, motorbike and 30 litres of water with minimal water then i cant take the wife never mind the other 4 or clothes.

Every cloud...
