For that small of a RV, I would highly recommend a combo washer and drier like the Splindide 2100XC. Smaller and less weight.
A few of the larger RVs can be converted so that a 240-volt drier can be used.
More than likely your HR is 30 amp, so you are stuck using 120-volt appliances.
Does your TT have water and drain connections for a washer/drier is a starting point. If not, how will you get water, power and drain connection to the location?
Another point is you want an outside vented drier, so it will need to have an access to an outside wall for the vent.
