Do Travel Trailers Have Generators?

Generally speaking, the answer is no; most pull-behind travel trailers do not come with built-in generators. Since most campers are equipped to run on campsite power, you can power your camper with a portable generator when shorepower is not available.

The only RVs I have seen with built-in generators are some 5th wheels and motor coaches.

Does that mean you can’t use a generator if you want to? You can use a generator to power your travel trailer if shore power (power pedestal at campsites) is unavailable.

Portable Generator To Power your RV

Since travel trailers have very low power consumption, finding a small portable generator that will power what you need is not hard. Read our recommendation for the best RV generator.

What Size Generator for a Travel Trailer?

Determining the size of the generator, you will need for your travel trailer will depend on just what you intend to tower. Most campers typically power an air-conditioner, refrigerator, television, and lights.

How many watts does it take to run an RV air conditioner?

For a 15,000 BTU a/c unit, you will probably need a 3,300-3,500W generator. Keep in mind generators have a starting watts rating and a running watts rating.

A 3,500W generator will start your a/c and keep running with some wattage to spare for other uses.

Adding a Generator to a Travel Trailer

If you want to add a generator to your travel trailer, look no further than Mod Your RV. Their website has dozens of DIY modifications you can do to your travel trailer. Adding a generator is explained in this article by Mod My RV right here.

Another option you may have is to optionally order your dealer to prep your travel trailer for a generator. This will involve running all the necessary wiring, installing a transfer switch, and installing all of the needed outlets for a proper connection.

This will cost you extra, but it is probably worth it in the long run.

Summary

Finding a travel trailer with a built-in generator is nearly impossible. You can either use a portable generator or mod your RV with a gen set. Before choosing a method, you have to determine your needs first.

Will you be mostly boondocking or campsite RVing? How much wattage will you need? Once you know this, making the right decision on a generator for your travel trailer should be easy.
