Can't offer that much advice except:
1: Do it
2: Strongly consider leasing
3: Do it
4: Don't listen to those who say you can't/shouldn't do it
5: Do it
Better to do it and have a terrible time than to spend the rest of your life wondering how great it might have been. It will be a fantastic experience for the boys who, even if they don't appreciate it right away, will find out just what a beautiful world this is and just what a terrific Dad they've got.
