2026 39' Newmar Grand Star 3948

2026 Newmar Grand Star 3948 – Stock #8448

On Order – Arriving July 2025

A little about this Grand Star:

The all-new Newmar Grand Star is a great option for those that want a little more out of their Super C experience. Newmar has set the bar for luxury and performance with the 2026 Grand Star.

This coach sits at a desirable, 39’ in total length, but features a bath and a half floorplan. Newmar has always set the bar by thinking differently and out innovating the competition. We love that you can fit, a stacked washer and dryer, a king bed, two bathrooms, opposing seating, a pantry, and a nice kitchen galley, all within 39’ in overall length. The short length is a perfect match with the Freightliner S2RV Chassis and the Cummins 6.7L Diesel Engine. With a 12,000 lb towing capacity, it’s great for flat towing your F-150, or towing your ATC Car Hauler.

We picked over $50,554 in options on this one. But we picked them with intentionality. A few highlights include:

All Electric Upgrade Package ($36,498 Option) This gives you a host of upgrades including:
- 640-amp hours of lithium batteries in lieu of standard 6-volt lead acid batteries
- Upgraded 3,000-Watt Hybrid Inverter
- Hydronic Heating in lieu of Propane Heat and Water Heater
- Induction Cooktop in lieu of Propane Cooktop
- This package alone makes the Grand Star stand apart from the competition at this price point!

Theater Seating in lieu of a Sofa Sleeper – A personal favorite of ours. The theater seats are the most comfortable seats for the Grand Star. With the over-cab bunk, the king bed, the dinette sleeper, there is still room to bring the family along!

Egress Door with Ladder System – A safety innovation from Newmar that we absolutely love. This gives you an extra exit point in the rear bathroom with a full size door and ladder, making it easier and safer to exit the rear of the coach in case of an emergency!

You can put your name on it with a 10% deposit. Give us a call, and we can tell you even more about it, and the process of making it your coach. See you out on the road!
