You make a great point about the RTT and how often I use it. I currently will not be able to spend that much time out in the "wild" to make it a feasible purchase, but maybe in the future. It is great to hear that you and your wife like overlanding together and separately. I have been a single dad for about 15 years now, and most women I have encountered are more "cityfied" and do not like roughing it much. Which is fine as my son and I really like going camping and now we are expanding to overlanding.
My daughter is 8, and LOVES camping with me. She gets mad if I go without her, but she understands this is how dad gets his alone time.
My wife has been more of a natural progression. She started off going on day trips with me, then we started doing overnight trips. She drove off road for the first time a few years ago, on a really easy road. Then I started letting her choose whether she wanted to drive the Fronty, or the X.
The we did the Idaho BDR last year.... She had so much fun, when we got back, she bought her 02 X all by herself.
She's decided it's time to start building it and getting some mods installed now. Everything that happens to the rig is her call. I'm merely here to provide insights and help facilitate things.
I just wanted her to go with and be comfortable, but she's all in at this point, which is amazing.
