Decoding RV Trailer Sizes to Match Your Camping Style

The Right RV Trailer Size For You

RV trailer sizes range from compact and agile to spacious and luxurious. Choosing the right one depends on how you travel and how far off the grid you want to go. At ABC Upfitters, we match your trailer size and camping style with the perfect off-grid power system. Whether you’re starting simple with the Launch Package, stepping up to the Borderland, or going all-in with the Apocalypse Package, we’ve got a solution to keep you powered up and adventure-ready. Read on to discover what size and setup are ideal for your boondocking goals.

Understanding RV Trailer Sizes & Power Requirements

When it comes to RV trailer sizes, the selection you make will directly impact your onboard power demands. Understanding the relationship between your trailer size and power requirements is key to a comfortable, worry-free road trip.

Here’s a quick overview of common trailer length categories:

  • 20–25 ft: Compact and nimble. This size is great for solo travelers or couples
  • 26–30 ft: Mid-sized with more amenities and space for small families
  • 31+ ft: Spacious and often equipped with full kitchens, one or more HVAC systems, and entertainment systems

The Right RV Trailer System For You

At ABC Upfitters, we help you match your solar and battery systems to how you actually use your RV. 

Essentially, we assist you in selecting the right RV trailer system for you, based on your camping needs. However, all of our packages listed below (see graphic) can typically be installed in any size RV – no matter how you choose to camp.

Find Your Fit

Choosing the right trailer package and power system starts with understanding how you travel and your camping style. Here are a few smart tips to guide your decision:

  • Estimate your typical power usage: Track how often you use your AC, fridge, lighting, and other appliances while traveling off-grid. This gives you a baseline for battery and solar needs.
  • Set your off-grid goals: Are you planning quick weekend escapes or week-long boondocking trips? The longer you’re off-grid, the more power you’ll need, and the more important solar recharging becomes.
  • Plan for growth: If you’re starting with a smaller system, make sure it’s expandable. Having a clear upgrade path (like the one offered in ABC Upfitters’ Launch and Borderland packages) ensures your system can expand in the future.
  • Work with our team of experts: ABC Upfitters is a professional installer who can help design a customized system tailored to your trailer layout, and power goals.
