tablet mounting options

so i have a samsung tab 4 tablet and just purchased this charging cradle http://www.proclipusa.com/tablet-ho...t-swivel-for-hard-wired-ins-547632-19650.cmsv

now im looking for options to mount it in the vehicle similar to RAM Mounts.
The tablet has all my GPS/TOPO maps loaded for expedition travels, so it needs to be sturdy while offroad.
i've found this mount http://www.rammount.com/part/RAM-B-316-1-238U which could work but theres no word on how much weight it can carry.

this is going in a first gen (2001) tacoma. and i would like to still allow for plenty of room for the passenger

 

I can hold my iPad4 with Ramounts. Should hold weight just fine, but will bob a lot when off roading.
