06 Tundra 4.7 RWD worth going LSD or???

Sup TF I recently purchased a 06 Tundra XSP and I think I'm going to fix or replace my rear diff because it is load and I believe on the way out. I've done some research and some people are complaining about lock diffs being uncomfortable to turn at times ECT. I plan on buying a boat soon and think a LSD rear end will come in handy at the boat ramps ECT. I'm thinking of just replacing my whole diff with another OEM Toyota one with a factory LSD.. Im new to the truck world but been around cars all my life. Thanks in advance..

 

Adding an LSD and rear sway bar are two of the best things I've done to improve my 2002 4WD 4.7L, I will eventually add an LSD to my 5.7L RWD Tundra.
