Anyone have an old dog die while on the road?

We just experienced this last April while on a trip into Florida. Our Gizmo was 16, he'd been camping with us since a pup. He loved going. We are full timers now and we knew Gizmo was getting up there in age, his hearing was going and he had started to have trouble getting into bed and the rig. While at Homestead Fl we started to notice his back legs shaking while standing and we could tell he was in pain. We didn't want him to suffer, so we made the very difficult decision to put him down. We looked on yelp for references on the vets in the area and I also spoke to a groomer at Petsmart about where a good vet was in the area. We didn't need any health records when we put him down. But we do always travel with them for all our animals. We choose to pick his ashes up. We just didn't feel comfortable having them mailed. The cremation fees are based on the weight of your pet. Gizmo was almost 25 pounds and I believe it cost us about $250 for everything ( putting him down, cremation and container). Gizmo's box is on our shelf and will go with us wherever we go. We miss him dearly but know he is in a better place.
