Thank you all for your help and suggestions. you all have been great and i appreciate all the possible solutions.
Just recently i have found and purchased a device that was originally intended to transfer pictures from my SD Card to my portable HDD.
This device: https://www.amazon.com/dp/B07M6P618P/?tag=rvf01-20
This fit my needs for picture transfer on the road without the use of a computer. However, it also can set up and run a DLNA server from the device with a external HDD attached with our shows and movies. So, we will be taking our Roku units for the two TVs and using the DLNA servers to access shows on the Roku much like we do at home.
Hopefully this will solve our issues. We will also be running a Plex server at home and access that when we have an internet connection. fingers crossed it all works like it is supposed to.
