Seems to me that there's been some good info presented, and some a little bit confused.
Many RV appliances (most ranges and furnaces and some water heaters) have no AC power connection at all, requiring only 12V DC and/or propane. Obviously 12V DC systems don't need to be changed to a different voltage for use in another country.
Line frequency differences make little matter to most appliances. Clocks run at the wrong speed, electric hair clippers and shavers with vibrating motors don't work properly, and old ferroresonant converters output the wrong voltage if the frequency is off, but otherwise most things work just fine including most appliance motors. Heating elements are not at all sensitive to line frequency; they would work perfectly with DC power even. Modern electronics are almost always rated for both frequencies (and often for a wide range of supply voltages these days).
Regulatory requirements for the AC electrical system are likely to be rather different, and it's likely that the load center and breakers are not rated for 240V use (only for 120V or 120/240V split phase use, where the nominal applied voltage is still only 120V). Converting it for overseas electrical specification involves more than just making sure the appliances themselves are suitable. Propane and vehicle and other safety requirements may also need to be considered. Plumbing codes may be different, and I suspect standard pipes and fittings are not the same, though I don't know for sure, which could make any repairs that may eventually be needed rather difficult to accomplish.
