IMO, don’t screw up your boat trailer unless you plan on keeping it forever.
It’s a solution with limitations even for you and will not be desirable to most buyers.
If you don’t trust your hitch with the required length of extension bar and don’t want to shell out for a super hitch, just get a heavy 2.5” receiver and a solid bar extension.
$300-400 will get you everything you need.
FWIW, I’ve been towing a 6000lb + boat/trailer for years on the OE receiver on the 07 Dodge with more than 500lbs tongue weight. Idk what it weighs but 2 men can’t lift the tongue of the trailer up.
