We bought our 2004 Ram 3500 CC short box SRW new with the intention of purchasing a 5r. We preferred the short box so it would fit in our garage. Unfortunately, most of the smaller 5rs manufacatured at that time were not tall enough to ride level, even with the axles flipped. So we ended up with a 23'TT. Another example of buying the TV before realizing what we could actually pull. At least it is a 1 ton.
Fast forward to 2012, found a 5r we really liked. Unloaded the TT, and purchased the 5r with a hitch and slider. The 5r has the rounded/angled front cap that allows for tight turning radius. Nearly 3 seasons into it, we have not had a need to use the slider, and we do get into some very tight spots, especially boondocking. But I do rest easier knowing I have the slider should we find ourselves needing to use it.
Good luck to the OP, lots of varying ideas and opinions, but isn't that why we come here:)
