I have a 2017-Vegas 24.1
I recently installed the HWH straight acting, telescoping, power extend, spring retract jacks
They are controlled by the 225 series Joystick controlled system
Its mounted against the driver's wall, behind the cup-holder area.
I paid $3K for the unit + $1,500 install.
I decided to go with this unit verses the Kick-down jacks + automated system due to the extra cost.
I saved about $1000-1500.
I'm very pleased with the system.
