I tend to agree with most of the OP's - don't buy just to satisfy the grandkids. Look for a size that you are comfortable with, both in living and driving and maneuvering around small roads, campgrounds, parking lots, etc. Most smaller class C's only have 2 seat belts for the dinette or sofa due to weight capacity of unit. Larger C;lass C's with V-10's have more capacity. If it just going to be you and wife 80% of the time, go with the smaller rig, if that is your preference. Bad weather can be dealt with inside, although after two days, I'd probably move somewhere else to find better weather. We travel in a 24' class C, wife and I, small dog and 2 cats. Getting ready to leave on a 4 - 5 week trip in a few days, so I suppose if this is doable, then grandkids would be too, for a fe days. Good luck,
