I did lots of searching when I bought and converted a cargo trailer to a small toyhauler with full living quarters.
My neighbor races go karts for a living so he also has a big gooseneck. both of us after searching felt that Pace trailers best fit our needs in terms of high quality and features.
15 years later, both of us agree, that the Pace trailers have done what we expected. He put over 100K miles on his first bumper pull then updated to a bigger gooseneck that probably has 30K miles on it now.
Wells cargo was also near the top of our lists, but both of us felt the Pace trailers were finished better.
