Ideally yes. But there are two major differences between a local and a remote call:
1) A remote call – inherently – fail. However, some local calls never fail. Either because they are designed to never fail or because you have done the required checks before executing the call. A remote call can fail because the network is unreliable and there is no way around that (?).
2) A remote call – inherently – can be very slow. Again because of the unpredictable network. A local call may be slow as well but usually either because everything is slow or because it just takes a while.
So if you have a call that may or may not be local you still have to treat it like a remote call. Right?
I think having a certain set of calls that may or may not be executed locally is not that bad. Usually it will just be a handful of methods/functions that should get this "function x(executeLocally = false|true)" treatment - which is prob. an acceptable tradeoff.
It happens all over the EU. Police will randomly select semis and camper vans and ask them to follow them to a weighting station. For example in Germany they are spread out along the Autobahn - same in France and NL.
The weight is usually determined by 4 scales (1 for each wheel).
Then they look at your papers which also includes information about max load at the front + back.
If you are over weight you have to get rid of the additional weight and if you can't they will seize the car. You get fined. It does happen.
It happened to me twice in Germany, once in Norway and once in France.
No you are incorrect. There are 2 maximum masses: the one from the manufacturer and then the legal mass limit. Legal mass limit = MIN(3.5t, max mass according to manufacturer) or more precisely MIN(max_mass_you_are_certified_for, may_mass_according_to_manufacturer).
It is not about + or - 10 kg. But things definitely add up. 10kg here - 10kg there.
Solar panels is something that is under the control of whoever buys the vehicle. You have almost no influence of the vast majority of what makes up the van.
You also risk insurance issues when your car is over weight.
3500kg for the whole vehicle including interior + 100L of water + 100L of Diesel + 50 L of gray water + 2 Passengers + 1 shower + 1 bed + 1 kitchen + 2x11 l gas etc.
As I mentioned: A typical camper van is borderline at 3300 kg already so you have 200 kg for cloths, food, water to drink, bedding, etc. It even matters whether or not you gained 10kg during winter or lost 10kg.
16kg equates to about 2 lithium ion 100WH batteries
1-2 bikes for bike tours
1 grill + extra gas for a barbecue
etc.
So you can decide between those or a conventional solar panel or you just pick panels that weight less then you can have both.
In Germany (and I think in the EU) you have a max. weight for cars of about 3.5T (~7716 pounds). You can drive cars that weight more than that but then your speed is limited to (I think 80-100km/h), you have to pay (more) toll and more importantly you have to get a special drivers license in most cases (cost + time).
Camper vans usually get very close to that limit. Even if the van has only 2 sleeping spots. Weight is definitely an issue there and most camper vans sold these days come with a solar installation on the roof.
With 100W of solar you can expect some additional autonomy as a camper. 200W is considered more than average solar for small camper vans in the EU.
A typical 200W solar panel weights in at around 10-13 kg + maybe 1-3 kg for the additional bracket.
11-16kg is something you would think about.
Thats also the reason why flexible panels are already used for some camper vans. They also have the advantage than you can put them on un-even surfaces.
The VW Grand California for example can be ordered with a flexible panel at the front side:
1) A remote call – inherently – fail. However, some local calls never fail. Either because they are designed to never fail or because you have done the required checks before executing the call. A remote call can fail because the network is unreliable and there is no way around that (?).
2) A remote call – inherently – can be very slow. Again because of the unpredictable network. A local call may be slow as well but usually either because everything is slow or because it just takes a while.
