    GMC Sierra Tow Vehicle

    Greetings,
    I am new to the forum and newer to Grand Design. Yes - I know the 220RK is discontinued - but - I just purchased one. Coming from a pull behind, this is my first 5er. Question - I have a 2018 GMC Sierra SLT. It has. 6.2 with 3.23 rear axle. Does anyone else tow this 5er or similar, with this type of TV. Again, just purchased it and picking it up Friday. Hopefully I won't find any surprises.

    Have you had any issues with this set up? I also have a 2017 Sierra with the same gears and engine.

    No - In fact I just came back from about a 3 hour drive, one way. It handles it just fine. I leave tow haul mode in. Plenty of power. I had a few hills with a 5% grade, I had the cruise set at 58 and it dropped down to about 55 and then shifted down and climbed right back to 58. On a windy day, I can feel it, but a normal drive, really don't feel it.
