You don't need a dually to enjoy the RV lifestyle. Generally a 1-ton SRW will often safely pull up to about a 35' 5er. There are a lot of choices in that weight bracket that can keep you from needing a dually. You will obviously need to crunch the numbers for each set up as there are a lot of variables between trucks and trailers. High profile 5ers start out heavier so just pay attention to the GVWR of each.

When you get to 35' and above the weight will also jump accordingly and a dually may be your best, or only bet. It all really depends on the rig you want in order to enjoy the RV lifestyle.
