Caskey had little to worry about on fitness following a game that was played in two 20-minute spells and a final 40-minute session, with players subbed on and off at regular intervals.
The majority named to play in the trial turned out with the notable exception of Taihape first-five Tom Wells, who was suffering a slight back injury.
Hunterville halfback Nick Tipling replaced him at No10 in Wednesday night's Country starting line-up.
Town spent most of the first spell in Country's half and were rewarded with a great forward push over try scored by Border's John Laurie at lock.
This was followed shortly after by another fine forward push that allowed his teammate Kamipeli Latu at prop to score.
The match see-sawed and Country countered with a try from Taihape's Dane Whale wearing the fullback jersey.
Winger Jaye Flaws from Taihape dotted again for Country down before midfielder Kameli Kuruyabaki (Pirates) scored for Town.
Late in the match Utiku Old Boys winger Michael Nabuliwaqa snaffled the ball out wide and ran half the field to score.
The difference between the two sides may well have come down to kicking duties with Ruapehu's Zyon Hekenui showing the best form for Country, missing just one shot at goal, while clubmate Tautahi Rawiri kicked two conversions and a penalty, although missing two other shots.
Rawiri plays for Ruapehu, but lives in Wanganui hence his selection for the Town side.
Post-match, Caskey was reluctant to single out players or positions under scrutiny, but was more than happy with the ball skills and commitment shown by both sides after just one training session together.
"It was a reasonably fluid, fast-paced game and there was plenty of commitment from both sides, which was great to see.
"Ball retention was a bit of a problem from time to time, but I think that was more to do with players slow to the breakdowns. These are things we can work on.
"Overall I was pretty happy with what I saw tonight," Caskey said.
Country 26 (Kapene Paki [Ratana], Dane Whale [Taihape], Jaye Flaws [Taihape], Michael Nabuliwaqa [Utiku OB] tries, Zyon Hekenui [Ruapehu] 3 con) beat Town 22 (John Laurie [Border], Kamipeli Latu [Border], Kameli Kuruyabaki [Pirates] tries, Tautahi Rawiri [Ruapehu] pen, 2 con).
