-As much as I'd like to have something that we could use for weekend/holiday trips, the reality is that if we stay in the house, then my wife will continue to work, and my weeks off are spent piddling around the house, and now, taking care of the baby.
Someone had to straighten me out when my kids were babies---If you're their Dad, it's not babysitting. ;)
If that week off is getting to you, maybe finding an RV project would be right up your alley. While the baby is still small and is sleeping most of the time, you will have some free time.
I wouldn't make any drastic lifestyle changes with a newborn. The baby will be doing that for you.
