99 astro and Trailmanors

We've pulled a 3300 pound popup loaded, with the Astro, only extras are the Transmission cooler I installed. Have the electric brakes that came with the popup. Travelled the Smokies, Blue Ridge Parkway and up and down the east coast several times. Does anyone have experience with your TrailManor and a Astro as the tow vehicle. Thanks for any info you might provide.
