Trustworthy and kind QH looking for new partnership

Joe (AKA Jerry, AKA Pinky Little Fritz) is a 13-year-old purebred Quarter Horse.

He stands 1.55m (15 hands) tall and is a copper chestnut.

Joe is a sensitive and affectionate horse who enjoys human contact. Extremely kind and respectful, he is a joy to be around every day.
Joe knows the basics of Western riding; in the arena, he is very focused and refined.

He also enjoys it.
I learned western riding with him, I was coached for a year while leraning and he was always very patient with me in the arena .Then I went on to do mostly trail rides. I ride regularly but never extensively, so Joe was never overworked...
He would be perfect for an intermediate to experienced rider looking to transition to Western riding (for example).
On trail rides, he has plenty of energy while remaining perfectly manageable. He can go absolutely anywhere: water, trucks, motorcycles, bicycles... He rides alone or in company.

He has already done 4-day treks, and his sociability makes him a very easy horse to take anywhere (he loads easily in a van). Joe currently lives in a pasture with other horses 24/7, but a more secure, more human-friendly, and slightly more comfortable environment (especially in winter) would suit him better. For example, a stall at night and time outside during the day.
The sale is not urgent; I will take the necessary time to find the best match.
