TT depreciation per year according to kbb? Cargo trailers

Sorry, didn’t pick up on you being the same guy procrastinating about unicorn cargo trailers.
Btw, isn’t what you’re looking for commonly called an inline? 7’ wide and wheels tucked under.

Although this has literally zero to do with the depreciation of a TT.
Other than, if you want to ensure quicker depreciation on a cargo trailer, one sure way is to market it as a homemade TT. No one wants someone else’s happy homeowner handyman project.
