My Anaconda with x2 SRV in a 4H Hangar, 5D Fighter bay plus fighter, x2 AFMU plus cargo and heat sinks does 62.53ly. That's a 6A G5 Mass Manager FSD. Plus other mods such as 5A PP G5 Overcharged and Stripped Down, G5 Clean Drive 5A Thrusters and G5 5D Engine Focused Power Distributor. Others who have gone for a super lightweight build can get 70ly+
My AspX carries one SRV, a 32t Cargo rack, some Heat Sinks and the gubbins for scanning everything that comes my way but nothing else. With G5 deepcharge 5A FSD, 4D G5 Thrusters stripped down and a 3A PP G5 stripped down I get 49.95ly with a fully laden hold and a max jump range of 58.57ly. I'm sure there are far better set-ups but I tend to use my AspX as a Bubble-bouncer collecting materials, running the odd mission and generally to-ing and fro-ing around the place.
38ly could easily be improved, although its already enough to take you anywhere you want to go, but as mentioned previously it does very much depend on what's in your suitcase for each trip.
