We have owned our 2002 Vanguard 9.5 TC for about 8 years now and grown to love it. Purchased in very good to excellent condition , we are now considering something with a slide out. Currently, we are looking at a 2008 Lance 1181 for more floor space.

We carry our TC , which weighs approx., 2600 lbs on a 2002 F-250 LWB SRW 4x4 with Firestone air bags. It's a 7.3 diesel and typically get about 11-12 mpg on average.

I would expect that going to a heavier TC would impact the MPG that we currently get. The Lance 1181 is approx. 3600 dry. For us the question is , is the slide out worth it for the decrease in mpg.

So. my question goes out to anyone with a similar truck but with a heavier TC than we have, what kind of average MPG do you get ?? Thank you
