RV permit question, going my way?

Thanks for all the info. I usually use the truck crossing and hesitant to use the crossing in downtown Nogales. Is it safe to drive a 30’ RV thru the downtown border crossing going south and coming back north? I usually avoid driving thru the villages due to narrow roads and heavy traffic. I have walked around Nogales on both sides of the border and didn't think it was a good way to go. I used to cross near El Paso but over the years there were fewer and fewer places to stay overnight so switched to Nogales. I will be leaving my scooter stored in Tucson as I don't want to go thru the hassle of getting an extra permit. A friend of mine in Chapala rode one around town and fell while making a turn on the cobblestone street and broke his leg. That was always in the back of my mind when I posted this. I used to ride my bike but after the 3rd time of almost being hit by drivers while in a bike lane or riding on the berm, I gave up. The buses have become overcrowded in Chapala, you never know when one will arrive and when it does it is packed. I think they cut back on bus service as it seemed there were fewer buses running last time I was there. Ron
