Welcome to the forum, sweet ride!
Cool you have the kids racing XC, it’s great to teach them suffering and overcoming mental obstacles at such a young age.
I grew up racing motocross and have gotten deep into cycling/MTB in the last 15 years, Cat 2 and scared to make the jump to Cat 1 as I’m lucky to get 5 hours a week in the saddle.
I tell my wife that our kids will be racing MTB, not moto. I don’t know that I can watch my kid destroy his body like I did mine.
Make sure you dive deep into the Gen 3 forums, you can find a lot of things to look for to get fixed before your warranty is up. I had to get a number of things straightened out when I got the truck, but it’s been bulletproof ever since! Enjoy.
