Pole holder in car
Does anyone have any suggestions how i can secure this plastic seat belt trim so i can add weight to it (i have a pole that i need supported) or how i can secure something to hold the pole from inside?
The other end of the pole is supported on the cab shelf and with a hook on the handle about the rear passenger door.
Asking here as car campers are a creative bunch and so i can take my pole leaving space for my bed/ sleeping
Thanks
