You and your family will have so much fun with your TM. I wish that we'd had ours when the kids were smaller, but we had other rigs that were cool too (but definitely not as cool as the TM
).
To me the most fun was when we first brought it home and we got to "make it ours". All the pots and pans, the bins, figuring where you can store stuff, what you need to camp with; and it changes constantly as the kids get older. I look back at our first TM pictures when my son was 12, he was so much smaller, and now he's this big 17 (soon to be 18) year old. They grow up so fast.
I hope you have lots of wonderful family camping trips in your TM and that it serves you well.
If your tires are old, get new ones. This has been our biggest problem so far. And do the wheelwell retrofit. My DH thought I was being a pain in the kazoo when I asked him to help me do ours, but after our first blowout, he was thankful that we did it.
Happy TM trails to you!
