Grand Design is one of the most respected names in the RV industry, and this 2015 Momentum 350M shows you why they earned that reputation. This toy hauler fifth wheel comes with three slide-outs for maximum interior space, an 11-foot garage with a built-in fuel pump, and one and a half bathrooms so you never have to wait in line. The Momentum line was designed for serious toy hauler users who refuse to compromise on living quality, and the 350M floorplan delivers a true residential feel even when you are parked miles from the nearest town. Three slides open up the interior dramatically, and the fuel pump in the garage means your toys are always ready to ride. This is the rig for the family that camps hard and lives well. WHAT WE LOVE: - Grand Design build quality is consistently top-rated by owners and reviewers - 11-foot garage with fuel pump keeps your toys gassed up and ready - Three slide-outs create a wide-open, residential-feel interior - 1.5 bathrooms is a game-changer for families and groups WHAT TO KNOW: - Originally listed at $58,995; now priced at $49,995 - 2015 model; inspect seals, roof, and slide mechanisms during your walkthrough - Fifth wheel hitch required; verify tow vehicle rating At $49,995 with estimated payments around $348/mo with 30% down, this Grand Design Momentum is a premium toy hauler at a mid-range price.

What’s included in this price →

We’ve sold 20,000+ units since 1986. We know what a good deal looks like. More importantly, we know what a “good deal” looks like three months later — usually it has a wet carpet, a lien no one mentioned, and a trailer that failed inspection on the highway.
You can find it cheaper. Someone always lists something cheaper. But cheaper assumes the title’s clean, the engine checks out, the trailer’s road-legal, the paperwork makes sense across state lines, and someone answers their phone after the transaction. We don’t make those assumptions. We verify them.
Gas isn’t getting cheaper. The season doesn’t wait while you look for a better deal. We hear it every spring: someone who looked last fall, decided to keep looking, and spent another summer on the dock watching other people’s boats go by.
Get the toy now. Use it now. Two years from now you could be in the water or you could still be looking. Gotta pay to play — and Havasu people know which side of that equation they want to be on.
The desert roads don’t get any less crowded. Every season you wait is a trip you didn’t take. — One price. One handoff. Ready to go.

This is an RV for people who have been planning the trip long enough. Here's what we'd tell our own family before they spent this kind of money with us.
Why This One?
What's Included
- 3 Slide-Outs
Most buyers who spend real time on a listing page already know whether this is worth their time. The specs check out or they don't. The price makes sense or it doesn't. The story feels right or it doesn't.
The question that usually moves people from "maybe" to "yes" is one you can only get from a real conversation:
"Has anyone else been seriously looking at this recently?"
Call (928) 453-8833 and ask that directly. We'll tell you exactly where things stand — and if it makes sense, we'll get you set up to walk through it.
What Our Customers Say
Bought a pre-owned pontoon from the team at The Boat Broker. Deal agreed same day, no games on price. Their shop did a full inspection and detail before I picked it up — everything was exactly as described. Have bought three boats in my life and this was the easiest by far.
We drove from Phoenix after seeing the listing online. They went through the full inspection, handled the title and registration, and had everything squared away before we made the trip back to pick it up. The boat was in perfect shape — exactly what was in the listing, no surprises. Staff was patient and never pushed us.
Called on a Thursday, came in Friday, and agreed on a price for a Mastercraft on Saturday. Their shop spent the following week doing a complete inspection and detail before we took delivery. Honest brokers, clean paperwork, and the boat was in perfect condition when we picked it up. Highly recommend for anyone shopping in the Havasu area.
Most buyers who get this far end up owning the unit.
Not because they were pushed into it. Because they did exactly what you're doing — and the research did the work.
If something about this Grand Design still feels uncertain, that's the thing to ask — not something to sit on. The buyers who look back with no regrets are the ones who stopped overanalyzing and started asking. On the road this season. The campsite is waiting. The only variable is whether you're in this one or still looking.
At this point in life, the question usually isn't whether — it's which one. And you've already narrowed it down.
