"They'll have plenty of motivation for it.
"We've learnt the lesson well and truly, several times, you never take the foot off with these fellas.
"You want to work hard and be kept honest."
While Wanganui have had the edge on King Country in recent seasons – the last loss being in the 2014 regular season, followed by a draw in 2015 - repeated trips into a warm Te Kuiti have seen a familiar script of the visitors shooting out to comfortable leads, only to have the home side come back strongly in the second stanza, if not quite enough to win.
After Wanganui felt the heat in Napier against a Hawke's Bay Development XV, Caskey knows conditions could be just as hot for this game at the Taumarunui Domain in October rugby on the Central Plateau.
"It's pretty much what you'd expect at this time of year.
"It was good news, really, on the injury front.
"We might be able to have more than two backs on the bench, if it's these hot days, and we've had some before."
After the backs' injury mini-crisis, both Ethan Robinson and Cody Hemi were able to do light training without heavy contact on Tuesday, Hemi a real possibility to make his Wanganui return, while utility back Tyler Rogers-Holden, impressive in Napier, comes back after being unavailable last Saturday.
The two players who got a little banged up at the Shannon Domain in winger Vereniki Tikoisolomone and prop Wiremu Cottrell are both still running around, as is hooker Dylan Gallien as he recovers from his rib injury.
With players coming back or settling in, given a handful of them made their first-class debuts last week, Caskey's focus has been on making sure all offloads go to hand after a scrappy opening half against Horowhenua-Kapiti.
"Just a lot of things we need to tidy up – people not quite being in the right place and doing the jobs they needed to be doing.
"It let us down in the set-piece. It's everyone nailing their roles and how they should be done.
"But you've got Alekesio Vakarorogo, Semi Vodosese, Matt Ashworth all learning, you can't expect it in 1-2 weeks."
On Wednesday, Caskey was watching footage of King Country's 34-22 away win over East Coast but, in perhaps a bit of foxing, King Country did not play their trump card in that match.
Therefore, tomorrow at home will be the 100th first-class game for their captain, the much respected Carl Carmichael, who had a solid career with Taranaki before heading back to his home province and playing another 36 NPC matches for them and making the NZ Heartland XV in 2014 and 2018-19.
Their head coach is former Waikato and Irish halfback Isaac Boss, who played Wanganui in Waikato's 2016 Ranfurly Shield challenge, and is working with a predominantly new-look team.
After Carmichael, the next most experienced players are Joe Perawiti and winger Stephan Turner, who will receive his blazer tomorrow, after playing his 25th first-class game for the union.
King Country's short representative season started with a 39-19 loss at home to Bay of Plenty Academy, before travelling to Masterton for a narrow 22-18 defeat by Wairarapa Bush, followed by the win over East Coast in Opotiki.
The Sir Colin Meads Memorial Trophy is to honour the 133-game All Blacks legend, who played in multiple Wanganui-King Country combined teams against international touring sides.
The trophy was the idea of WRFU historian JB Phillips, who approached Sir Colin's close friends, John and Ruth Palamountain, to commission it.
Permission was given by the Meads family, with son Glynn Meads representing them when the trophy, appropriately made of pine wood, was unveiled at Cooks Gardens in 2017.
Blair Symes of Display Associates was able to construct the trophy at short notice to be ready for that game.
Glynn Meads lifted the veil on the trophy in the presence of Wanganui and King Country rugby officials, along with New Zealand Rugby Union president Maurice Trapp.
