Choosing the Right Portable Generator for Camping in the Rocky Mountains
Rocky Mountain camping is a little different.
Whether you're spending a weekend near Estes Park, dry camping in the San Juans, tailgating before a Broncos game, hunting on the Western Slope, or taking your RV through Rocky Mountain National Park, reliable portable power can make the experience more comfortable and convenient.
The challenge is finding a generator that's powerful enough for your needs without hauling around more equipment than necessary.
At Rocky Mountain Generator Supply, we've helped campers, RV owners, and outdoor enthusiasts throughout Colorado find the right portable generator for years. As an authorized Cummins Onan dealer, we carry portable generators designed to deliver quiet, dependable power wherever your adventures take you.
How Much Power Do You Actually Need?
Before choosing a generator, consider what you'll be powering.
For tent camping, you may only need enough electricity for:
- Phones and tablets
- Portable refrigerators
- Camp lighting
- Small cooking appliances
- Laptops and electronics
For RV camping, your power needs can increase significantly:
- Air conditioners
- Microwaves
- Coffee makers
- Entertainment systems
- Battery charging systems
The right generator depends on how you camp.
Best for Tent Camping and Lightweight Travel: Onan P2500i

With 2,200 running watts and quiet inverter technology, it's ideal for powering electronics, lighting, portable refrigerators, coffee makers, and other campsite essentials without disturbing the peace and quiet of the outdoors. The compact design makes it easy to load into a truck, SUV, or camper van.
The P2500i is especially popular with:

Best All-Around Generator for RV Camping: Onan P4500i
If you're looking for one generator that handles most Colorado camping situations, the Onan P4500i is hard to beat.
Producing 3,700 running watts and 4,500 peak watts, it delivers enough power for many RV air conditioning systems while remaining surprisingly quiet for its output. Remote start capability, extended run times, and RV-ready outlets make it a favorite among travelers throughout the Rocky Mountain region.

Maximum Flexibility: Onan P4500iDF Dual Fuel
Colorado weather can be unpredictable. That's one reason many campers appreciate the Onan P4500iDF.
This dual-fuel generator allows you to run on either gasoline or propane with the flip of a switch. Propane can be especially convenient for campers already carrying tanks for cooking or heating, while gasoline provides flexibility when you're on the road.

- Long stays at dispersed campsites
- Mountain cabins
- Emergency backup power
- Travelers who want fuel flexibility
Serious Power for Campgrounds, Worksites, and Backup Power: Onan P9500DF
Some situations require more than campsite convenience.
The Onan P9500DF delivers substantial power for larger RVs, multiple appliances, jobsite use, or emergency home backup. Like the P4500iDF, it operates on either gasoline or propane, giving users additional flexibility during extended outages or remote adventures.
This generator is well-suited for:
- Large RVs
- Hunting camps
- Food trailers
- Remote worksites
- Home backup applications
Consider Colorado's Unique Conditions
Camping in Colorado comes with unique challenges that aren't always a factor elsewhere.
Higher elevations can affect engine performance. Mountain weather can change quickly. Remote campsites often mean fewer opportunities to refuel or replace equipment if something goes wrong.
That's why reliability matters.
Cummins Onan portable generators are backed by the same engineering expertise trusted by RV owners, homeowners, and businesses around the world, along with a nationwide support network when you need assistance.
