Hey, @MLore-2129!
In order to download the IFTA report, you need to go to Compliance > IFTA Report. From there you will see a Filters option where you can set the date range and select individual assets to run the report on.
If your vehicles are already split up so that you have your cars and trucks assigned to different Groups, you may be able to use the Groups dropdown to choose only that group instead of having to select your cars individually. (I say "may" because I am currently having some difficulty getting the Groups filter on that page to work in my demo database.)
Anyway, hopefully this helps you get what you need.
Reach out if you have further questions. :)
Best,
Joy B
