Not a perfect match for RV and tow vehicle. You need either a bit more tow vehicle or a bit less trailer.
Based on my experience with my '99.5 Ford F-250 CrewCab two-wheel-drive diesel and 25' 5er with one slide, I suspect you'll be overloaded with that 5er. You'll have more than enough power and torque to drag that trailer over the mountain passes on interstate highways, but you'll exceed the GVWR of the tow vehicle.
My pickup's GVWR was 8,800 pounds, and the 5er GVWR was 7,900 pounds, and the 5er was usually loaded right up against the GVWR. But on the road my F-250 GVW was usually 400 to 700 pounds overloaded over the GVWR. That diesel engine is a heavy dude that absorbs payload capacity, and a 4x4 would be even worse.
Per NADA, the 2000 Alpinlite 29 has weight (lbs) of 9,446, or about 1,500 pounds more than my 5er. So you can expect about 250 pounds more hitch weight than I had. My payload was only Darling Wife and a small Pomeranian, along with a toolbox full of tools.
That Dodge is a wonderful tow vehicle for an 8,000-pound TT, but a 9,500 pound 5er will probably overload it. The Alpinlite 5er is nice, but it needs a 3500 truck to tow it without being overloaded.
