everyone has told me that my best fuel mileage on my diesel is at hwy speeds of 70mph. Can you tow a 5th wheel safely at that speed?

At highway speeds, the weight doesn't play into it as much as some people believe on close to level ground. There, wind resistance is the biggest fuel burner. We upgraded trailers (1000 lb more) this spring and so far our mileage has remained pretty consistent (9.8 to 10.3 mpg).
It looks like the weight does have an effect though as I have an identical tow vehicle and my MPG normally runs 10.5 to 12 mpg. My GVWR is 14K and it looks like yours is 16K. San Angelo to Goshen my average was 11.3. On the return it was 10.7 (winds out of the south). I normally run at 62 or the speed limit if lower. I use Cetane fuel conditioner.
