If you want to buy a crawler, go with a TXT or Chodbuster is much much better than TLT.....
To be honested, both TLT or F350 needs a lot of modifications in order to start to "craw"! You'll be spending at least another 1k - 2k in order to make it crawable...
There is nothing in the market that you can buy and craw.... all of them needs modifications so you can buy anything you want...
But if you do modification, go with CB............. because the chassis is easier to modifiy than the F350 chassis.
"買 CB 又驚佢車底唔夠高" --- This shouldn't be a problem in CB........... But many people buy CG just for the front and rear axles... everything else is DYI or buy the Junfac kits...
