Default 1999 Roadtrek 200 mileage

Hello, all! We are looking at purchasing a 1999 Roadtrek 200 with a 454 Chev engine. The unit has 85k miles on it.
I have been scouring the web trying to find out if it requires premium fuel. I am also wondering if it gets much worse fuel economy than a 350 CID would get. Would appreciate any input. Thanks!

Default 454 is nearly 30 percent larger in displacement

YES..at 29 percent larger displacement and a big block V8.....I would expect it to use more fuel.... Can't imagine WHY you would need premium fuel???

It's all about condition at this point..I wouldn't get all wrapped up by the "low mileage" aspect.....ask for service records...and find out who owned it and for how long......

Fuel economy will be around 15 or so, maybe a few miles less.... depending on where and how you use it...

Good luck....

Default '2012 Airstream Avenue Suite (6.0L Chevy)

First long trip in our '2012 Airstream Avenue Suite (6.0L Chevy). Think Roadtrek 190 and you'll have a pretty good idea of the engine/chassis/size.

On our trip this past May from Texas Coast to Yellowstone and back we averaged 15.6 mpg up and 14.7 mpg on the way back. Half of the trip out was mountains, sightseeing, and twisty roads. Most of the way back was comparatively lower and basically level freeways at 70 mph but some headwind. Amazed that the mileage going out was so good considering the grades we pulled at elevations up to 9000 ft.

The Chevy 6.0L engine is a beast.

Keep in mind they are probably using Imperial Gallons, not US gallons. So factor in about 1.2 US gallons for 1 Imperial gallon.

And they may be equipped with teeny 1.3 liter turbo diesel engines.

On my last 5,000+ mile trip from the Texas Coast to Maine and back, the readout in my Chevy Express 3500-based Airstream Avenue read 15.8. I have determined it is about 3-4% optimistic over real world mpg, but still, I'm very pleased with 15+ mpg. Especially since I mostly drive the speed limit and don't baby it. Love the power from the 6.0L v-8 engine.
