fuel economy

We have a 2019 suburban premeir 4x4 5.3L factory tow and 3.42 rear axle ratio. Thinking about a 2012 Keystone RV Passport 2510RB Grand Touring dry weight 4839 pounds. Anyone have a similar weight trailer and what mpg they are getting with what type of TV. Please no one with a diesel TV only a gas vehicle.

Thanks

Paul

Someone will be along shortly to tell you that if you have to worry about mileage you can't afford RVing ...... 10, 9, 8, 7 ........



But, we pull at a 22' Keystone at about the same weight with a 5.7 liter Tundra and get around 9 mpg.

HTH ......

Pretty much all gas trucks are getting 8-10 mpg towing travel trailers. Length and weight of the trailer matters less than the height and width. Pulling that giant sail at highway speeds is what sucks all your fuel.

First thing to do is FORGET the dry weight. What is the trailer GVWR?

As noted, most gas tow vehicles will get anywhere between 7 and 10 mpg depending on load, terrain and how heavy your foot is.

You do not buy an RV and expect good gas mileage.

Guessing you will probably be looking at between 8mpg and 10mph depending on wind and road conditions.

Do yourself a favor and don't tow without a TPMS (tire pressure monitoring system) on those trailer tires. A blowout will ruin your day with that combination.
