Has anyone ever seen a regular wheel base van with a slide-out?
I see all the big RVs and pull trailer have them. Why couldn't a van?
This has surely nothing to do with the length of the vehicle but with the whole construction! A Van body is made of steel: strong (in terms of crash test and torsion) but with a minimum cost (for manufacturer) and weight.
RV´s have an custom made body for
their specific use. If it includes a side-out it is planned before the construction is made. A steel Van body only works in the way they are build by the manufacturer! If you cut out e.g. the roof you will loose most of its strength. If you cut out a side rail from the inside (like for installing a window) you will loose strength also.
Both is done very often witch does not mean is is a good idea.
If anyone wants to do this it is surely possible but for how many compromises? It is better to start with something new instead. Thought the benefit of room will surely not be in good relation to the costs!
Don´t get me wrong: I like the idea but it is from a logical pov pretty bad.
Though a van body like a E350 is very aerodynamic. This means - sadly- that the sidewalls are much narrower at the top of the vehicle. My personally favorite way of internal allocation is much different than a typical US Van like a Sportsmobile: I like to NOT climb into the roof. I don´t like to fold a bed either. To get as much room inside as possible I want to have the bed at the rear but across the vehicle! I need roughly 6 foot witch I can get at the middle of the body height but not at the top!
Solution is this:
