The wife and I have talked, she actually surprised me because she said she doesn't want to sell the camper and is planning on still going camping this summer with the twins!
On the vehicle front, we started looking at a different vehicle that will be our traveling rig. We went to 8 different dealerships to see if we could find something that we liked. Our criteria was seating for 7. We initially started looking at the Expedition Max which checked all of the boxes with plenty of seating and cargo capacity but then the Mrs had reservations about the sheer size of the rig. We looked at several other mid-size SUVs that has seating for 7 and while she felt more comfortable driving it, there was almost no cargo capacity. We went back and forth but eventually compromised with getting two vehicles. The larger vehicle now so we can travel and haul everything we need and then in a couple of years, we will upgrade her car to a mid-size suv that has the seating capacity for 7 but just not the cargo capacity.
For future camping trips, if we grow out of the camper, I think we will likely rent a travel trailer versus buying one and selling the camper. Realistically we won't be doing a lot of trips in the near future and by the time the twins are old enough to really have freedom to travel, the older girls will be off to college. I don't see the point in buying a TT for what would be just a limited period of time in my books.
