English to Spanish Social Sciences Psychology Dog Training

I am not sure about the meaning in this informal English sentence of the expression "rolled up". It is a book about dog (puppy) training, written in very coloquial English.

"That’s how I want your puppy to be. Living life purely for pleasure, not a care in the world.
I think back to the magical adventures we’ve shared: catching ‘bad guys’, searching for drugs, singing along to the radio in the van on our way to the training field, and generally just being with each other. We’ve covered thousands of miles and made more B&B hosts doubt their own judgement when we’ve rolled up than I care to remember. I’m so excited for you. You and your puppy are going to make your own magical adventures".

My attempt:
"Pienso en las mágicas aventuras que hemos compartido: jugar a atrapar a los «malos», buscar drogas, cantar al ritmo de la radio en la furgoneta de camino al área de adiestramiento y, en general, simplemente estando juntos. Hemos recorrido miles de kilómetros, haciendo dudar al presentarnos a más anfitriones de B&B de los que me gustaría recordar".
