I've only kept one fun vehicle stock, and it was a a 2011 GT500. Only reason it stayed stock was due to trading it in for my first raptor. Only had it for a year and was thinking TVS + exhaust lol.
Before that was an endless money pit my 2004 Lightning which had pulley swaps, full exhaust, blown engine, 2.3KB and a 2.6L KB.
My current Raptor has 3.0's and I have the stock wheels in boxes for now.
Next year it'll have deaver//icons with bumps stops.
Then maybe a supercharger lol
Way I see it I get enjoyment out of modding vehicles. Keeps them feeling "new" in a sense.
I probably draw the line at mods that make permanent changes to the truck. Like cutting a lot things off or once it's on it's going to be pricey to get it off type of stuff
even then, just depends on the budget.
