Cirrus 820 Truck suggestions

I love the looks of those campers. Nice choice!
I'll start by saying this probably isn't the answer you'r intending to get, but what are your goals with the new truck? (Aside from assuming your current F250 isn't a CC as you mention upgrading to a CC)

I ask because, with the exception of newer Ram 2500s with rear coil springs, virtually any other 3/4T or 1T from the last 20 years will handle the load of a mid weight camper like the Cirrus pretty similarly.
So in a 1 ton srw, honestly, pick your favorite brand, color and engine. More of a concern or difference there than how it will handle the camper.

Interested in this as well. I am planning on buying an 820 and an F350 to replace my travel trailer and F150 next year, and have been researching this combo for a long time now. I have similar planned uses. I figure a SRW F350 should be the sweet spot for this camper, really don't want to go DRW as this will be my daily driver. Most newer F350's (gasser CC SB 4x4) payload ratings are in the 4100+lb range.

Zero need for a dually for that size camper.
