I have spent a fruitless hour trying to find the total weight added by the AL-KO HY4 levellers without success. However I looked under the van whilst their engineer was checking the system and it looks light. The four legs are aluminium and the control unit is a small plastic box.
However, as gus-Lopez advises, if you are going to change a wheel you will need a back-up jack or two, or axle stands.
Whilst looking for the weight I read that the levelling jacks work in tandem; one will not work on its own so to change a wheel either the whole side, or the front or rear will be raised. In this case I assume a jack will have to placed in the middle, or two jacks are needed. This is to avoid unnecessary stress on the body of the Motorhome.
This brings me to a question: if only one jack is used to lift the vehicle enough to change the wheel, will the motorhome chassis twist and damage the integrity of the motorhome body? If so this would be another good reason to fit levellers.
Re: the last two posts, the instructions on using the levellers is clear. They must not be used as the only means of lifting the vehicle when changing a tyre. If they failed a person could be injured and I am sure an insurance company would not accept liability.
