Purchase of a MH is a major financial transaction. First rule is to never sign any papers or give any money until after you drive the vehicle AND all outstanding issues are fixed to your satisfaction.
Once you sign and give the dealer money, you LOOSE ALL YOUR LEVERAGE!
In other words there is no incentive for the dealer to fix anything, but before you sign and give money YOU HAVE CONTROL. That makes all the diference in the world. Which position do you want to be in???
Before signing and giving money YOU can walk if YOU want to. After you sign and give money, YOU cannot walk without consequences. NOT GOOD, YOU want to always be in a position of CONTROL or POWER!
