Well, it is great to be out and away from the city with wife and dog--really relaxing, if you have the right rig.
Large tanks aren't needed, unless you are going to try camping without hookups.
50amp service is a necessity. Be careful of tires and wheels--a lot of mfgs only put on the bare minimum required to carry the weight on the axles, with little margin for error/wear and tear on the tires. Disc brakes/17.5" tires are a big help in avoiding blowouts and stopping easily.
