I pulled my 9500 lb Reflection with a 2009 Tundra and was quite happy with the performance and handling. Towed for a year and 6000 miles and no issues. Would have been happy with another Tundra or another 1/2 ton but I keep vehicles for 10 years and can see a 40' 5th wheel in that time frame so upgraded to a 3500 SRW.
If you are not happy with the current Sierra Denali with the 6.2 then you won't be happy with another one either. Skip the 2500 and just go 3500 SRW and that gives you more payload and options if you upgrade later on.
