I understand the cons of Thor's RUV vehicles. However, this is a unique concept and for some justifies some tradeoffs. There are some pluses to your decision:
- 8k hitch rating
- outstanding wheelbase/length ratio
- 25.6 is the only floor plan they offer on the E450
- Heavy propane/plumbed appliances not in the slideout
- Unlike F53s, E- Series Fords can be converted to 4WD
