New Truck Question

I currently have a 2013 Ram 1500 w/3.55, tow capacity is 8700lbs.

We are looking at upgrading travel trailers to a Kodiak 30' BH. Dry weight is 7300, loaded is 8900.

My Ram already struggles with our current trailer that weighs 8000 loaded.

Welcome to the forum.
I assume its the 5.7 Hemi with a tow rating that high. With the 3.55 rear axle ratio its not hard to see why the trucks performance struggle with 8000 lb trailer.

I am considering upgrading trucks with the trailer upgrade. I know going with a 2500 is probably the way to go but in the interest of money I have been looking at the Silverado w/3.42. It's rated to tow 9200.

My question is will it struggle like my Ram does?

Moving up to a 2500 with the same small block gas engine won't gain much as far as engine performance. The heavier 2500 truck can struggle even more with the small block gas engines.
Now if you move on up to a 2500 6.4 Hemi with say the 4.10 ratio then you will gain some very good towing performance plus more payload capacity.

Another possibility if you want to stick with a 1500 is the 1500 GM with the 6.2 engine with the NHT package. Check it out.
