We mainly do Road Trips, anywhere from "long weekends" to two+ weeks. We have been using our small SUV and staying at hotels, but now that we have the time (we can travel at least 50% of the time if we want) , we want to go at our own pace, and stop and stay when something interests us anywhere along the way.
Right now we plan to do Route 66 (again), but all in one trip Chicago to LA, but branching out for interesting places, so that will be an easy 3-4 week trip.
We mainly camp at County, State and National parks, will most likely be driving to hike and see something almost every day, as compared to sitting in an RV Park for a week, though we will be using those (for the amenities such as laundry, dumping, pools, etc.) every week or so.
I am used to tent camping (and back or SUV camping) so I am sure we will boondock on a fairly regular basis when it is doable.
We are planning to stay on the small (?) side of Class B, no big 24 footers, so I can park at home and use it for 2nd vehicle, take it to the county parks with the bikes for the day, pretty much use it at the drop of a hat, so we are trying to keep it in the 19.5 - 21 foot range, for ease of parking, etc.
