Is there a reason I need gutters on my mobile home?

We recently had that debate, while renovating an older home. The engineers decided that the UPHILL side of the home needs the gutters (and downspouts) to take the water away from the foundation. The lower side has no gutters and hasn't had them for over 100 years.

So, if you have a surface drainage problem, keeping the rain from the roof in a smaller area (downspouts) may make your foundation last longer.

If the daily dew drop does not get on your siding or on the concrete patio. It is not the rain that is the big problem. Everything gets wet in a rain. It is the daily morning drip. It will rot any wood or grow fungus and mold. If you have a roof overhang of a couple of feet and a flower bed, you don't need gutters.

If the home has skirting I think you can survive without them.  If it is on a block foundation I'd leave them.  As for cleaning them, I believe they make some simple attachments for a leaf blower that is designed to blow out gutters from the ground. 

go ahead. and you'll want to make certain sure that removing them doesn't leave an opening for water to seep in and begin the process of rust. I recommend epoxy or bond-o for that

Without gutters water runoff will run down the walls of your home and likely cause leaking inside the walls, possibly inside the home.
