You Asked, They Answered — Introducing the Coleman 18OG
Isn’t it nice when an RV manufacturer makes practical changes spurred on by direct customer feedback? In many ways, that has been the bedrock of Keystone’s approach to relaunching the Coleman lineup since they brought it under their wing a couple of years ago, leading them to introduce an all-new, off-grid-capable version of their family-favorite 17B floor plan. New for 2026, the Keystone Coleman 18OG brings impressive solar and suspension upgrades to this layout, designed in direct response to customers who asked for a “17B with better solar capability.”

Here’s the rundown of the major changes and additions:
- Three 220-watt, roof-mounted solar panels for a total of 660 watts of solar capture capability
- Two 100-amp-hour lithium batteries in a heated enclosure
- A 2,000-watt inverter and inverted outlets throughout
- A 30-pound tongue-mounted LP bottle (upgraded from 20 pounds on the 17B)
- Higher ground clearance and rugged off-road tires
- Upgraded suspension with shocks
- An upgrade from a 4,000-pound axle to a 4,400-pound axle
- A 46-gallon fresh water tank (upgrade from the 21-gallon tank on the 17B)
Inside, the Coleman 18OG delivers the same interior comforts that attract many families to the 17B—stacked single bunks for smaller kids, a larger front bed for parents, a cozy dinette that converts for extra sleeping space, a functional kitchen, and a small rear bathroom with a larger-than-average 30” x 36” shower.
Additionally, Keystone made several smart layout changes to improve livability. They added a driver’s side baggage door for easier access to the storage area under the bunks. They extended the kitchen countertop for more prep space and installed a 32” TV above it for optimal viewing from pretty much anywhere inside—front bed, bunks, or the dinette.
Speaking of that dinette, they added a 56” x 29” window over it and increased the size of the overhead cabinets above it, as well as those in the kitchen.

Kevin Horoky, National Sales Manager for Keystone Coleman, shared how the 18OG proved itself in real-world conditions:
“We used this camper at outdoor shows completely unplugged and were running the A/C in the middle of the day in Arizona — powered strictly from the sun. That was one of the best demonstrations I’ve ever seen of how usable this unit really is. It’s not just capable on paper. It works in the real world. On top of that, you’re getting higher ground clearance and upgraded off-road suspension. So now you’re pairing serious solar capability with a platform that can actually get you where you want to camp.”
Overall, the Keystone Coleman 18OG showcases smart, practical changes that dramatically improve this trailer’s off-grid capability. And the best part? Keystone did it while staying true to one of their most important core principles: affordability.
