Sounds like you have a solid plan to me .... getting to spend the summer doing what you want to with the Jeep and getting EXACTLY what you want in the 23 Bronco when it's ready ... you will have a solid trade and you wont miss a beat
Get the Rubi and if the Bronco is still calling you after a year sell it or trade it to get a Bronco if you can swing it. You’d lose a few thousand driving it for a year but they hold their value like crazy. Enjoy yourself while you can
