DRV doesn't advertise weights simply because when you order a trailer from them there are too many variables to deal with. You can get a unit equipped with 2 - 6 volt batteries and a 1000 watt inverter or one with 4 - 6 volt batteries and a 2800 watt inverter. Adding options like a washer and dryer or a generator are going to change the weights, You can have a third AC unit put on the roof, all these changes are going to have an effect on GVW. Pin weights on DRVs are always high, ask any one who owns one.
If you've ever looked at one of their build sheets you'd see what I'm talking about. There are a ton of options that can be added or changed or as some DRV customers refer to as "deleting" certain items.
Go onto the DRV forum and ask those people about weights, general consensus will be "heavy". :B
