HOT and COLD water is backwards on my 2022 Solitude

[ForBruce]

In America all faucets have the hot on the left and the cold on the right.... or you turn the single handle in that direction.

While Grand design did it correctly in the kitchen and bathroom faucet.. the shower is backwards. And being super close to the water heater I fear any guest might scold themselves.

So I could pull the unit off the wall , not knowing if there is any slack in the connections and possible open a can of worms or just reverse the hot and cold in the basement.

I chose the basement because the shower lines are separate from any sink.

see the photos they are self explanatory.
