Practical Motorhome Eldiss Aspire and loading margins


Recommended Posts

Colin Leake - 2011-02-20 5:03 PM Just a little tip on public weighbridges. Most charge for each weight recorded so if you want to know the total weight plus front and rear axle loadings pay for only the front and rear axle loadings and add the two to give total weight or have the total weight read and only one axle getting the reading for the second one by subtraction.

Or find one at a builder's yard (or similar) where they receive or dispatch bulk goods.  The norm is there are two weighings per ticket, one for a truck as it arrives (empty, or full), the other for the same truck as it departs (now full, or empty).  If you speak to the operative and explain what you want, he will set the machine as appropriate. 

For a collection, for example, you drive the front wheels as far on as possible, leaving the rears off the platform.  Weight 1.  Then drive the whole van on.  Weight 2.  The calculation the machine would then normally do in this mode would be weight 3, the collected load.  This would be  weight 2 (the departing weight) - weight 1 (the arrival weight) = weight 3 (the weight of the goods collected).  However, in your case it will do the same calculation to give total weight (weight 2) - weight on front axle (weight 1) = weight 3 (the weight on rear axle).  So both axles, and actual laden weight, all on one ticket, for just one charge.

MAM = maximum allowable mass (as you posted)

Which was preceeded by MTPLM

MTPLM =maximum technical permissible laden mass

Which, itself was pre 1998 known as MGW maximum gross weight)



Civil Servants running out of work, so let's change some definitions - that will cause some confusion & keep us in a job :D :D


Thanks Flicka - why use one PAA (Perfectly Adequate Acronym) when three will do! :-S

Probably not that significant, but that 2,788kg includes the driver at a nominal 75kg.  Might be better to aim at the 2,753kg figure, add actual weights of driver and passenger to that, and deduct from MAM.  However, your MRO is higher, because of the fixed items you've added, and you need to allow for the ± 5% tolerance on MRO.

Weighbridge check desirable in unladen state, if you really want to know payload!  :-)

BTW, the sum of the axle maxima will always exceed the MAM, otherwise loading the vehicle within the load restrictions would become almost impossible.  Re-plating to the sum of the axle maxima is possible, but it is almost invariably one, or other, of the axles that reaches its load limit before MAM is reached, so any payload gain is liable to be illusory.

Yup I know, but interesting theory nonetheless! :-D We did go to a weighbridge back in May last year:
Just thought I'd mention that we went to the weighbridge today, we did the readings twice and they were (max permitted axle weight in brackets):Front (max 1750): 1330/1360 (don't know where the extra 30kg is from!)Rear (max 2250): 1850/1850Total combined weight of: 3180/3210 - I'll use the higher figure of 3210kg to be safe.As we were on our way back from a car boot sale we weighed the stuff we'd bought, and shopping too, which came in at 67kg of 'non-motorhome stuff'. So the actual weight without this stuff, would have been nearer 3143kg, leaving an unused payload of 357kg.As we'd gone purposely with the van almost fully loaded (including canoes, bikes, etc plus the dogs too) just some food and clothes to go in, plus filling the water up for full 'holiday mode', so I guess that'd add around 130kg, lets say 150kg to be safe, making a total weight of around 3293kg, giving a remaining unused payload of 207kg.
