At 35’ you do not need a diesel engine so go to 40’ so you have no choice plus you’ll save a step or two and a fair amount of money. I made the mistake 20 years ago believing 36’ was max for public CGs… not true even in a big rig.
Went to the Tampa Super RV show last month and again was not impressed with the new DPs…poor fit and finish plus very heavy and surprisingly poor CCC. Agree 03-08 (if it has a 06 engine) we’re good years I’m partial to the Monaco products, especially the bigger ones with a tag axle… 40’ or more. Great handling rigs and well built.
