Relationship between lengths of TV and TT
Is there one? Is there a ratio that needs to be observed, or is it entirely a matter of GVWR-payload-tongue weight?

Most Semi trailers are 53-feet long, most of the tractors pulling them have a 13-feet long wheelbase (about the same as an F150 Supercrew). So in the same context a 25-feet long trailer should only need a 6.5-foot wheelbase. And actually, you have some semi tractors pulling two or even three semi trailers. My point is, There is no ratio that needs to be observed. But the longer the better it will handle.
You are right, and in addition most over the road class 8 tractors weigh about 1/3 of the fully loaded trailer weight (about 60k lbs+ trailer and load). This assuming a total GCVWR of 80,000 lbs.
