The vast majority of RV buyers make their purchasing decisions almost completely on their budget, the floorplan, and features. But if you look a little closer there are some big factors that you might want to consider.

Build Quality.

Build quality is a big concern for many people, but when they go to pull the trigger on a new or used unit, they often ignore it.

Lots of brands build units for every price level, and quality can vary depending on the individual group that built the unit on a given day, Remember, most RV’s in the same price range are built with the same methods, so it’s really often down to the individual unit.

During the buying process, look for features that will last longer, like solid wood cabinetry, ceramic toilets, and solid surface countertops. Look under the bed and in the pass-through storage to see how the unit is really built.

Fiberglass trailers are generally built with welded aluminum framing, while metal-sided trailers are usually a wood structure. These things aren’t necessarily dealbreakers, but they should inform your buying decision

Find peace of mind in your purchase by getting an inspection on any new or used RV before you purchase. Similar to a home inspector, certified RV inspectors will spend hours going over every little detail about your unit, so you can make sure anything that isn’t up to snuff can get repaired before you accept delivery. You can find an inspector at NRVIA.org.

Cargo Carrying Capacity

Probably the most overlooked spec on any RV is the cargo-carrying capacity (CCC). What good is that giant refrigerator and cavernous storage if you don’t have the ability to use it because you can’t carry enough weight

Check on each and every unit you tour, especially if you intend to bring a lot of stuff with you. And remember, water weighs 8⅓ lbs per gallon, so that 50-gallon water tank on your new fifth-wheel weighs over 400lbs when full.

Tank Capacities

Speaking of tanks – what is the capacity of the grey, black, and freshwater tanks? Some RVs have generous tanks, with well-thought-out ratios between the sizes, others seem to just put whatever tank fits in.

When considering tanks sizes, it’s important to ask yourself how you intend to use them. If you plan to do a lot of camping without hookups, your most important consideration is your freshwater tank, as the grey and black will usually not fill before the fresh is empty.

That said if you intend to primarily use campgrounds with water hookups and no sewer, generous grey and black tanks can keep you camping longer without heading to the dump station. And remember, bigger RVs don’t necessarily have bigger tanks.

Conveniences That Make Regular Use Easier

Don’t be fooled by inexpensive add-ons like outdoor speakers and WiFi prep that you’re better off purchasing on your own. Instead, consider the features that are a bit more difficult to install after the construction phase that really make life in an RV a lot easier.

For instance, a tank sprayer. There are lots of aftermarket add-ons for flushing out your black tank, but a built-in tank sprayer is much more convenient and works better than most.

Winterization kits that bypass the water heater when it’s time to fill the lines with antifreeze are shockingly not standard, and a must-have.

Additionally, look for easy access panels to get to water connections, as they often need tightening. An electric tongue jack and electric stabilizers or a full leveling system require quite a bit less physical effort than anything that involves a hand crank.

How the Storage Actually Works

It’s easy to see if an RV has a lot of storage space or not, but can it be opened easily? Or does it involve lifting up a massive piece of plywood with no lifts or hinges?

Will it be as easy to lift that bed open and get your clothing out every day with an upgraded heavier mattress with bedding on it? Can you actually fit full-sized plates in any of the cabinets or drawers?

Is there enough counter space to set out a toaster or coffee maker? Can you envision where you will store shoes when people enter? Where will your garbage go?

Other questions to ask include laundry storage. How about your towels? These are top items that don’t often have a convenient space, so try to map out in your mind how you will deal with them.


Slides can drastically change the space inside an RV, but make sure to look at the unit with all the slides in, and make sure you are comfortable with that.

Some, especially in motorhomes, will still allow you to access everything, others will block off bedrooms, bathrooms, and even the kitchen. Blocked areas are important to assess ahead of time, especially if you plan to pull over and use your rig for the bathroom or to make a sandwich.

Slides are also a common point of failure, whether it’s the motors, alignment, or leaks. Multiple slides compound those issues and take longer to bring in and out at the campsite. But that doesn’t mean they should be avoided. Just make sure they’re built well, and that they operate properly upon purchase.

It’s important to know how to maintenance a slide. Pay close attention to the technology used. Hydraulic slides are the most reliable and most expensive. That said, the frame rack & pinion slides are common, and reliable, displaying very few issues if installed correctly and maintained.

Many manufacturers will point to cable slides as reliable and high quality – but customers will point to lots of failures, so they’re used less and less. Schwintek and other in-the-wall systems work fine for smaller, lightweight slides, but should be avoided on heavy, large slides.


30 amp RVs can connect to virtually any RV park connection, while 50 amp RVs can run a lot more things – especially multiple air conditioners. You can still use a 50 amp RV in a 30 amp site, but you may be limited to one air conditioner and have a hard time running multiple heating and cooling devices at once.

Understand how inverters work. If you want to run AC devices like a residential refrigerator or use your outlets on battery power, you’ll need an inverter. Some inverters are wired to run the whole rig, others are just for the refrigerator or an outlet or two.

You’ll also want to pay attention to where the outlets are. Do you intend to use your kitchen table as a workspace? Hopefully, there’s an outlet nearby. Will your coffeemaker or toaster’s power cord reach the outlet under the upper cabinets? Will you be able to plug your phone in next to your bed? Outlets are often one of the most overlooked items in an RV, and yet they are something you will use numerous times a day in various ways.
