I thought it prudent to get the motorhome weighed. A trip to the local weighbridge revealed its 2830kg in its stocking feet.
I have to admit this is a lot more than I would have guessed so I am glad I did it, The fuel tank was very low as well so to stay within 3500kg I am going to have to be very careful with what goes in!
Allowing for myself & wife, dogs and fuel I have about 400kg left of which up to 160kg will be water.
It is true the the chassis is a 4600kg variant so if the worst comes to the worst I can go over but it would be nice to stay below the magic 3500kg
