Keep in mind that the weights you are quoting are dry weights. No one tows at the dry weight. Factory installed options generally add around 500#, then add your "stuff". The GVWR of the Micro Lite 23 LB for example is 5316. Your ready to tow weight will be closer to that number than the dry weight number. That said any 1/2 ton will easily tow that trailer. Mine has a 4750# GVWR and it tows beautifully.

One thing I would look at is going to or negotiating for is load rating E tires. Most 1/2 ton truck or SUVs come with P tires. Es have much stiffer side walls which will enhance the tow performance.
While I can appreciate that this is pretty much a necessity with 30' trailers and/or a 3/4 ton truck, today's light truck/SUV "P" rated tires are not the same ones that are on your Buick Le Sabre. Nor are they the same as the ones they were putting on Suburbans 20 years ago. I've had several Suburbans. I used to change out the "P" tires for LTs right after I bought them.
On a 1/2 ton towing a modest size trailer I see no reason for the expense of an "E" tire. I've been running truck/SUV "P" rated tires on my last 3 trucks. Unlike car "P" tires, truck/SUV "P" rated tires can take more psi and have stiffer sidewalls. My Sierra currently has Yokohama Geolander AT/S tires. I run them at 48 psi when towing. They are fine. As good of a towing experience as any LT I've ever owned.
