Loaitayem, have you considered towing a small to medium size travel trailer with a van ? I think it might be a better financial and practical option for you.
Something like a ‘Tab 400’ is light with different floorplans that might work for you. Your tow vehicle could offer additional storage space.

If your class C rv is your only vehicle and it has to be repaired for mechanical or body shop work, it might be ‘out of use’ for a long period of time. They usually have to go to truck shops or rv shops with large doors and heavy duty lifts.
You would need to find transportation as well as housing for yourself and a dog.
I think having a trailer and a tow vehicle might be a better option for a lone person living with a dog.
A van or pickup truck can fit into any service station bay. Making appointment may be a lot easier and less expensive.

A trailer under or even in the 5,000-6,000 lb range can be towed by a van or pickup without having any special suspension upgrades in place.
In other words, you could lease new 150/1500 pickups every 3 years and always be covered by bumper to bumper warranties.
If you buy a used class C , you really do not know what you are getting into as far as reliability. You plan to live in this.
