If the surface they're sitting on stays dry, I think they'll probably be ok.

I'd try and get them off the ground at least a little. I found a pair of slugs in one of my tomatoes. As soon as they start to blush the bugs seem to swarm and having them on the ground leaves them more vulnerable. Good luck whichever road you take.

I've heard of using inverted egg cartons for melons - just an idea - would keep them off the ground without having to handle them too much.

I had a big white beefsteak-type tomato (White Wonder) that was hanging an inch or two above the ground. When it rained (or when I watered), mud splattered up onto the fruit and it ended up getting buckeye rot. I'm sure mulch will help prevent this, but it's probably best to support the truss by tying it up with some yarn or plant ties.

thanks everyone for the great suggestions.
just hate to lose them' they look so good
