wtb sunseeker 2500ts, 4winds 22b,e or 27' mid lazy daze

No,
I've spec'd it out. The sunseeker e450 chassis shows 22000 lbs gvcw with an unloaded about 11,500 lbs, similar to the lazy daze. The sunseeker comes with a 7,500 lbs hitch, the lazy daze a 4,000 lbs hitch. Highly doubt I will need to pull that much, can't see what I want to pull, and enclosed trailer with a bike or two in it and /or maybe a rzr. Also may on occasion flat tow a jeep. I don't want something rated to tow 4,000 lbs and have my load right at the limit.

Any construction, durability advice?

Thanks,
