Winter Route to South Texas

I-35 traffic generally from N of Denton, Tx down past San Antonio is challenging. A lot of construction from Waco south. If you choose this route and can time passing thru during off peak hours, then it might not be so bad.

If you're not on a time crunch, you could take I-25 all the way to El Paso, then hit I-10. But, you have to stop for a few days at the Davis Mountains. Alpine, Marfa and Ft Davis are the hidden gems of West Texas.

While enroute to our distant destinations, we use Passport America parks and stay there at 1/2 their regular price. The yearly cost to belong to Passport is $44 and can be saved back in two or three nights.

Here's some sample Passport America webpages:

Trails West RV Park, Shelby, MT

Thank you. We will check out Google maps. I have been looking at places to stop for the night. There seems to be many Casinos so are thinking that might be our best option. We r booked in at Weslaco and very much looking forward to our winter months.

Google Maps Trip from Saskatchewan to Brownsville

I've found traveling on a lot of our two lane roads is often better than our Interstate Highways. There's less traffic in most cases and lot fewer tractor trailers. You'll need to slow down while going through towns and occasionally come up on a traffic light. The route Google chose here includes some Interstate, some Federal Highways and some State highways. Only 2,235 miles and 35 hours driving time at the posted speeds so an RV may take a little longer. Enjoy the trip and I'll join you in Brownsville about the 1st of next year.
