My dad was in the Navy. He had a few favorites quips about boats:
There are two happy days the life of a boat owner
The day he buys it.
The day he sells it.
A boat is a hole in the water into which good money is poured.
After spending 2 1/2 years as a field service engineer at Marine Electric Company in San Diego, I could attest to his wise advice. I am not and never shall be a boat owner.
Likewise, the wise counsel of Dave Ramsey is to never buy a mobile home or trailer. It loses about 90% of its value in 5 years...well before most people can even pay for it.
