The hogtrough stuff mounts securely and is easy to reach but it IS beside the engine & exhaust. Whatever gets very hot, very quickly. I finally tried a 16oz Thermos with flip lid and it worked OK, but also got hot on the outside (stainless) which was OK with coffee and acceptable with water if you are not real picky.
Believe it or not, using the left side Hogtrough cup holder and the Bubba bottle I could keep ice in the bottle all day in 80*+ temps.
I loaded up the bottle with ice at nite in the motel, stuck it in the frig over nite and then filled it with water in the morning.
Doing it this way keeps ice in the bottle all day. Didn't come close with the cups included with the HogTrough.
I'm sure if you put one on the right side it might get warmer from the exhaust.
PS. I have a Bubba bottle here beside my chair, I filled the bottle with ice and water at noon today, it's now 2am and there's still ice
in the bottle. The house has been at 80* the whole time. Pretty amazing bottles.
