I don't worry too much about numbers until they get to the point of being a safety problem. It has become very hard to get DRV to own up to what they sell actually weighs BEFORE the customer gets his hand on it.
If you do get one, I would suggest that you get the vanity slide for sure, since you will spend a lot of time in it--little more space around the bed is a big help.
I have seen several DRVs being towed by SRW pickups--you might ask around if anyone has that setup--also, have you checked in on the SOITC forum--Suites Owners International Travel Club? Or the Thor DRV owners forum?
Also, there are some small options on tires that may help--check some tire companies for 18"/20" tires and load ratings that are higher than 3700. A set of 19.5" wheels/tires would help, but pricey.
