Buying a pickup truck used to just involve deciding how much towing capacity you wanted, but automakers today offer as many as 75 different versions of some models. That makes it all too easy to choose the wrong truck for your needs.

“You have to make sure you know what you’re doing when you’re buying a truck and what your needs really are,” says Karl Brauer, Executive Analyst at “Do you really need the most powerful engine or the biggest bed? Do you need an extended or crew cab, or can you make do with a regular one? You want to be realistic.”

It doesn’t help that today’s trucks come with a wide array of engines, cabin sizes, bed lengths — and prices. Some entry-level models list for around $25,000, but fully loaded-vehicles can top $70,000.

Here’s a look at seven common mistakes truck buyers make, as well as expert advice on how to avoid them. All dollar figures refer to the manufacturer’s suggested retail pricing as of September 2015 for base 2015 versions of each vehicle listed, excluding tax, title, destination fees and rebates.

1. Buying the wrong cabin size

Purchase a pickup with too big or too small a cabin and you’ll either waste money on more trucks than you need or find yourself or your passengers crammed into insufficient interior space.

Most trucks offer a choice of three cabin sizes:

  • Regular cab. These are the smallest option and usually have just two doors and front seating for two to three people. They typically lack rear doors and back seats.
  • Extended cab. These have both front and back seats, although rear seating is sometimes cramped. Some extended cabs come with full-sized rear doors, while others have only small, front-hinged ones or no rear doors at all.
  • Crew cab. These generally have four full-sized doors and generous front and back seats.

Different brands sometimes use names like “Quad Cab” or “SuperCab,” but those all basically equate to a cabin that’s either small, medium or large.

Brauer says you can pick the right cabin size by thinking about how many passengers you’ll typically have in your truck.

“Drivers who plan to carry multiple people on a regular basis should get an extended or crew cab,” he suggests. “But those who don’t should probably just stick to a regular one.”

Going with the smallest cab you need will save you money. For example, a regular-cab Ram 1500 lists for $25,660, while an extended-cab version costs $29,835 and a crew-cab one starts at $32,475. Buyers should also keep in mind that some extended- and crew-cab models come with smaller truck beds than regular-cab versions do, cutting cargo capacity.

2. Picking the wrong bed size

Trucks typically come with your choice of short, medium or long cargo beds. Again, picking the wrong one will either boost your price unnecessarily or leave you with a vehicle that’s too small for your needs.

Consider the Chevrolet Silverado 1500, which comes in either “standard-box” or “long-box” form. The standard box starts at $26,105 and has a 6.6-foot-long cargo bed, while the long box costs $26,495 but increases bed length to 8.2 feet.

Brauer says you can pick which size to get by thinking about what you plan to use your truck for.

“If you commonly haul seven or eight-foot-long cargo, you want to make sure you get an eight-foot bed,” he says. “But just as with cab size, you want to be realistic about how big the things you haul around are.”

He says avoiding a bed that’s longer than you need will not only cut your purchase price but reduce fuel costs and give you a truck that’s easier to both drive and park.

3. Selecting the wrong engine

Today’s trucks offer everything from surprisingly efficient 4-cylinder gas engines to 8-cylinder diesel behemoths, but picking incorrectly can saddle you with either an excess sticker price and fuel costs or too low a cargo and towing capacity. (Automakers rate trucks on both how much cargo vehicles can haul in the bed and how much they can tow with a trailer.)

For example, consumers who buy a Ford F-150 XLT can pay $31,320 and get a 283-horsepower V-6 engine that can tow 7,600 pounds, or they can spend $32,115 for a 365-horsepower turbocharged V-6 that can handle 12,200 pounds.

Again, Brauer says smart shoppers will honestly consider how much cargo capacity they need and buy accordingly.

“The rule of thumb is that you can probably get away with one of the smaller engines if you rarely tow or carry more than 500 pounds,” he says. “But if you plan to tow 2,000, 3,000, 5,000 pounds or more on a trailer, you’ll want to go for the middle- or upper-range of available engine power.”

4. Buying diesel if you don’t need it

Many trucks come with your choice of gasoline or diesel engines with diesel usually offering greater cargo and towing capacity but costing more money.

For instance, you can get either a gas or diesel engine on a Ram 1500. Base versions start at $25,660 and come with a gas-powered V-6 engine that can tow 7,600 pounds. But spending an extra $4,770 will move you up to an automatic transmission and a turbocharged V-6 diesel engine that boosts towing capacity to 9,200 pounds.

“Diesel engines have more torque, so they provide more pulling and towing power — and get better mileage, too,” Brauer says.

As with other truck considerations, the expert recommends picking your engine type based on how you plan to use your truck.

He adds that diesel no longer produces the engine noise, sluggish acceleration and smelly exhaust that it once did, so “the only real disadvantage is that they cost more upfront and you’ve got to make sure you know where to find diesel fuel.”

5. Buying too many (or too few) amenities

Some entry-level trucks barely come with air conditioning, while high-end models offer everything from perforated-leather seats to high-tech audio systems. Too many amenities will cost you an arm and a leg, but too few will leave you with a truck you don’t enjoy driving.

“You have to decide how much you need versus how much you want because pretty much everything you add will cost money, increase your insurance premiums and reduce your gas mileage,” Brauer says.

Example: A basic 2015 Ford F-450 SuperDuty Crew Cab XL lists for $51,910, while a top-of-the-line Platinum version starts at $69,250. (The 2016 model’s suggested retail price begins at $71,320.) That adds polished alloy wheels, a premium Sony stereo and plenty of additional luxuries — and if that’s not enough for you, available options include a $995 power moon roof, $300 heated rear seats and more.

6. Not considering insurance and gas costs

Sure, one dealer might offer you a great price on a given pickup, but higher insurance costs, fuel expenses, depreciation or other outlays might mean you’ll spend more in the long run.

“You always want to look at total ownership costs and not just price when shopping for a truck,” Brauer says.

Let’s say you’re choosing between an entry-level Ram 1500 Tradesman and a base Chevrolet Silverado 1500 Work Truck. The Ram lists for $25,660, but the Silverado costs $26,105 — theoretically making the Ram $445 cheaper.

But it’s not that straightforward if you factor in depreciation, fuel and other ownership costs.

According to KBB, you can expect to pay $40,496 in total out-of-pocket expenses to own the Silverado for five years vs. $41,957 for the Ram. That’s $1,461 savings with the Chevy — something to keep in mind when you’re debating which model to buy.

Another mistake to avoid is buying gap insurance from a dealership instead of your insurer. Gap insurance provides valuable protection during the early years of your truck’s life if you have a loan or a lease. Most lenders require that you buy this coverage.

If your truck is damaged while still new, gap car insurance will pay the difference between the actual cash value (ACV) of the vehicle and the current outstanding balance on your loan or lease.

If you purchase gap insurance from a car insurance company, it typically costs about $20 a year, according to the Insurance Information Institute, a trade group.

Buying gap insurance from a lender or dealership is much more expensive. Lenders typically charge between $500 and $700, according to United Policyholders, a non-profit consumer advocacy group.

7. Skipping the tailgate lock

Thieves may be able to unlatch and steal your truck’s tailgate in a matter of seconds if you don’t have a lock on it.

“It’s really quick — you don’t even need any tools,” says Frank Scafidi, spokesman for the National Insurance Crime Bureau, which found that claims for such thefts rose 31 percent between 2012 and 2013 (the latest years with data available).

The NICB says high-end tailgates can cost as much as $3,000 to replace, so you definitely want some sort of lock to protect your truck.

You can buy a model with a built-in tailgate lock, or you can pick up an aftermarket one at an auto-parts store for as little as around $12.

Even with anti-theft measures in place, you may discover your tailgate has been stolen or damaged by thieves. Penny Gusner, the consumer analyst for, explains the role comprehensive coverage plays in guaranteeing that a stolen tailgate is replaced or a damaged one fixed.

Comprehensive insurance basically covers situations that are ‘other than collision,’ such as theft, fire, vandalism or damage arising from natural events, like a hail storm,” she says. “It covers the theft of your whole vehicle or parts or equipment that are permanently attached or installed to your vehicle. So, a stolen tailgate is covered.”
