They are a pretty comprehensive tent, there's always seems to be something we would wish for or want to change, no matter which tent we purchase. :) ~ Ben
The SV-5 has more space in the external under cover living area. Other than overall size, the main difference with the RX-5 is that it has a removable zip in bucket floor for the annex, making it a fully sealed additional room. Unless that's specifically what you're after, the SV-5 would be the better outdoor living option ~ Lauren
