I have had a lot of exp with termites did you just get the cab or have you had it a while, if you have had it a while pull up the carpet by the stem wall you prob have activity right there & you have problems you will need to have this area drilled & treated I would also getting a bait station setup, thats what I did & i have been termite free for 10.00 years, $1500 to $2500 dollars, termites can only live in the ground so they are moving from your cab to the ground everyday
