From all I've seen and heard about Sprinters, they are a decent trailer, and becoming more and more popular.
About the width, 100 inches is stretching it a bit, depending upon your tow vehicle, using your rear view mirrors may be difficult, not to mention state restrictions on trailer width.
Although, if your driving through a state, I don't any police will be stopping you just to measure the width of the trailer. No. Indiana has a length restriction also, and I've seen hundreds of RV rig combinations that have exceeded that limit.
The problem comes only if your cited for a moving violation or involved in an accident. If you are too wide, "they" could claim you were liable for an accident because your trailer exceeded the state limitations. This is rare, but it could happen. (kind of like having no brake lights and someone rear-ends you.)
FYI (on a positive note) .... the double rear living room slide and bed room slide is absolutely WONDERFUL! We love ours!
Have you considered an Outback?
If this is the same one, here's the Sprinter and here's the Outback:
Sprinter 299RET WB (wide body):
Outback, not so wide body:
We have the 298RE outback, Absolutely LOVE it! You'll love either one too! We did not get the dinette. We got the free standing table and 4 chairs. We also changed positions of the two rocker chairs and the couch. This works much better when the slides are IN.
