Well, I just had to ask the following questions. I must have read hundreds of posts for this same subject area, but still wanted to ask anyway. Sorry if I offend anyone by asking, I've got a 1999 Dodge Ram, 5.9L V8 gas engine with tow package. not sure on the rear gear ratio. Owner's manual states max load 8,000. Looking to get a travel trailer (tired of the class a getting 6 MPG pulling tow dolly and car). Length somewhere around 27-30 feet and dry weight around 6,000 lbs. don't think I'll add that much more in weight when I pack. Thought maybe 7,500 lbs would be ok for this truck to pull. Thought I'd add air / helper shocks in rear of truck. Other thoughts are certainly welcome. Also, not really sure what brand to look closely at (except I don't want Forest River products). Thoughts? tks I've been looking and saw some really nice ones on this web site for used.
