For your first trailer buy a new-used directly from the owner and not a dealer .
The owner will throw in all of the little RV gadgets that he paid full retail for .
Most first time tt buyers are sellers by the 4th year .
They may not camp as often as they thought .
Or they may decide they bought too much trailer for their tow vehicle .
So the depreciation hit is less if they bought used , not new .
A longer trailer is a longer lever centered on its axles .
The lighter the tow vehicle the more the lever can move the tow vehicle .
Commercial trucks have their axles at each end of the trailer .
But not travel trailers .
Hence the need for a heavier tow vehicle if you choose to tow a longer lever .
We got it right on our 4th try .
