Went from a 28 ft 5er and truck to the sig C. Don't need a toad to go into town or wherever except for going from campground to the swimming hole we like where the C is too big to park. Mostly just take the whole C to wherever.
Do need to "mark" our campground site with a sacrificial folding chair and a plastic bucket while we are gone in the C, because the campground guys are a bit slack in setting their "occupied" signs. So far so good on that. Nobody swiped the chair and bucket (yet).
Lots of space in the bigger C so don't miss the 5er for room for "stuff"
We did have a smaller 5er that was too small for two of us (got the bigger 5er) and dogs, so that might be a problem with a Sprinter, don't know. The TC we have is too small for the two of us and the dogs for sure. It is just for DW and the dogs to go to dog events. For actual RVing it the C for that job.
You need to sit in one for a while or rent one and try it out before buying (that is a lot of money!). I suspect a bigger C would do you better, toad or not.
