I wouldn't worry about the 14 month old, He/she will be 24 months old before you know it and running all over the place. Not sure I would like making up the sofa every night for jr to sleep in, but that's just me. The Heartland is a nice looking TT though. You kind of answered you're own question when you said you want room for toys in the truck. One thing to watch though is the 322res has an abnormally low tongue weight from the factory. You may need to ,load the front of the TT up pretty good to get the min 10% for tongue weight. I went thru that with my last, which also was a Heartland product.
