Looking for the full spec breakdown and verdict on the Grab N Go itself? Read our complete Dyna-Glo Grab N Go review →
The Grab N Go’s defining feature is dual fuel flexibility: a 1 lb. cylinder for quick use, or an optional hose to a 20 lb. tank for extended runtime. That combination maps well onto RV travel, where you might want a grab-and-go option for a quick stop and a longer-runtime setup for an extended stay at a campsite. This page covers that RV-specific fit, not another spec teardown.

Comparing This to a Buddy-Series RV Heater
The Portable Buddy and Big Buddy heaters reviewed elsewhere in this hub cover similar ground: portable, indoor-safe, battery-free radiant heat suited to RV backup use. The Grab N Go’s main differentiator is that dual fuel setup being standard on the base unit, rather than something you piece together with a separate hose and filter purchase. Either family is a reasonable choice — compare specific BTU needs and existing brand loyalty before deciding.
Why Dual Fuel Flexibility Suits RV Travel
An RV often already carries a 20 lb. propane tank for its furnace, stove, and water heater. The Grab N Go’s optional hose can tap into a similar setup for extended backup heat, while the 1 lb. cylinder option keeps a lightweight, no-hose-required backup on hand for a quick overnight stop where connecting to the main tank isn’t worth the hassle. Few backup heaters in this BTU class offer both options built in as standard.
Battery-Free Backup for Off-Grid Stays
Like the portable Buddy heaters reviewed elsewhere in this hub, the Grab N Go needs no vehicle electricity to run, unlike an RV’s built-in furnace. That makes it a genuine backup for battery failure or a deliberate power-conservation choice during off-grid, non-shore-power camping. See our running a propane heater on battery power guide for the fuller picture.
Sizing for Your RV
At up to 250 sq ft of rated coverage, the Grab N Go suits a camper van, a small travel trailer, or supplemental heat in one section of a larger RV. For a full-size motorhome’s entire living area, it’s better used as supplemental or backup heat alongside the furnace rather than a sole heat source. See our furnace vs portable heater guide for that broader comparison.
Tie-Down for Travel
Secure the heater in a dedicated storage spot during travel, not loose on a seat or counter where it can slide during braking or turns. Disconnect any cylinder before driving, and if using the 20 lb. tank hose setup, disconnect that too rather than leaving a pressurized line connected while the vehicle moves.
Emergency and Winterizing Use
Many RV owners keep a portable heater like this one on hand specifically for winterizing trips or emergency situations where the built-in furnace isn’t an option. See our winterizing an RV with a portable propane heater guide for the precautions specific to that use case, which differ somewhat from occupied, everyday use.
The Buying-Decision Checklist
- Quick stops, minimal setup preferred? The 1 lb. cylinder option needs no extra hose or hardware.
- Extended stays or full-season use? The 20 lb. tank hose setup cuts down on cylinder swaps significantly.
- Running off-grid on battery power? The Grab N Go needs zero electricity, a real advantage over the furnace’s power draw.
- Winterizing or emergency backup specifically? Keep it stored and ready, with a full spare cylinder on hand.
Ventilation in an RV
RV ventilation requirements don’t relax just because the space is smaller — they matter more. Crack a roof vent or window whenever the heater runs, and keep a battery-backed carbon monoxide detector in the RV at all times. See our RV propane heater ventilation guide for the complete requirements.
Storage Space in a Smaller RV
A compact travel trailer or camper van has less storage room than a full-size motorhome. The Grab N Go’s built-in carrying handle and relatively small size make it easier to tuck into a cabinet or under a seat than a bulkier heater option. If you’re also carrying the optional 20 lb. tank hose accessory, plan storage for that separately, since it adds real bulk beyond the heater itself.
Cost to Run
A 1 lb. cylinder runs the Grab N Go for about 2 hours on High or 4 hours on Low. The 20 lb. tank hose setup extends that dramatically, up to 79 hours on Low per a full tank, which matters more for anyone planning an extended off-grid stretch than for a single overnight stop.
Maintenance Between Trips
Check the hose and filter for wear before each camping season if you use the 20 lb. tank setup, since that connection sees more use in RV travel than in occasional home use. Wipe down the radiant grille after any trip through dusty roads or storage in a garage. Confirm the tip-over switch and igniter still work at the start of each season, rather than discovering an issue on the first cold night of a trip.
Choosing Between the 1 lb. and 20 lb. Setups
New RV owners sometimes assume the 20 lb. tank hose setup is always the better choice, since it offers so much more runtime. For a trip with only a night or two of expected heater use, the simpler 1 lb. cylinder avoids the extra hose, filter, and connection points that add complexity without a real benefit at that scale. Match the setup to how long you expect to actually run the heater, not just to the biggest available runtime number.
Verdict
The Dyna-Glo Grab N Go’s dual fuel flexibility makes it a genuinely well-suited backup and supplemental heater for RV travel, whether for a quick stop, an extended stay, or dedicated winterizing use. It works best alongside an RV’s built-in furnace rather than replacing it in a full-size motorhome. For the complete spec table and verdict on the heater itself, see our full Grab N Go review.
