This will be a trip for both you to remember, don't forget to allow your daughter to take her own pics , even with those throw away cameras, she will have something to start her own scrap book.
That 990 will haul all you need. Wife and I did a 7 day trip to SE Utah on this 99 LC4 ADv R , camping all sleeps ,pics available if you wish.
Best of luck , you will have lots of awesome memories . We all look forward to your RR
