Trucks are great, but climbing in and out of a high cab gets old fast. Beyond gas and routine maintenance, adding exterior hardware like side steps can easily run $500 for a solid steel set. Prices tend to soften in the spring when off-road equipment brands run seasonal sales to clear inventory for trail season.
The goal is to get the hardware at a discount first, then split the bill into small bites. By using a promotional zero-interest window, you can spread that $500 cost over a year and a half without adding a penny in extra interest.
An intro window is a fixed payoff deadline, not free money. If you still carry a balance on your Citi Simplicity® Credit Card after 18 months, standard interest rates kick in on whatever is left, which quickly wipes out anything you saved during the spring sale.
