Is a travel trailer with a slide out a good idea for me?

Two points to consider,

Where are 4 to 6 people going to stay in a heavy rain.

According to the RV dealers I talked with at the last RV show, smaller trailers and non-slide out tailers are a niche market. That means less trade-in value in an already lightly depreciated market.

There is no doubt slide outs can be problematic, but I would not trade ours. Also some deeper slides can block access to the bath or kitchen when pulled in.

Good luck
